I. BACKGROUND
100031 Inflammatory bowel disease (IBD) refers to a collection of
intestinal disorders
causing inflammatory conditions in the gastrointestinal tract. Severe forms of
IBD may be
characterized by intestinal fibrosis, which is the accumulation of scar tissue
in the intestinal
wall. The primary types of IBD are ulcerative colitis (UC) and Crohn's Disease
(CD). Both
UC and CD are chronic, relapsing, remitting, inflammatory conditions of the
gastrointestinal
tract that begin most commonly during adolescence and young adulthood. UC
involves the
mucosal layer of the large intestine, and symptoms include abdominal pain and
diarrhea,
frequently with blood and mucus. CD can affect the entire thickness of the
bowel wall and all
parts of the GI tract from mouth to anus. CD symptoms include abdominal pain,
diarrhea, and
other more insidious symptoms such as weight loss, nutritional deficiencies,
and fever. The
prevalence of IBD globally is approximately 5 million and the disease affects
over 2 million
people in the US.
100041 The current standard of care for the treatment of patients
with moderate to severe
IBD are generally immunomodulatory agents that are anti-inflammatory. None of
these
therapies address fibrosis in IBD. Since the approval of the first anti-TNF
agent for the
treatment of CD in 1998, the availability of newer biological agents,
including anti-integrin,
Janus kinase (JAK) inhibitors, and anti-IL12/23 has improved the care of
moderate to severe
- 1 -

WO 2022/178159
PCT/US2022/016841
UC and CD (JAK inhibitors in UC only). However, none of these subsequently
approved
therapies have demonstrated significant improvement in effect size relative to
anti-TNF.
Moreover, among those patients who do respond, up to 45% will lose response
over time.
Current therapies used in the treatment of UC and CD apply a one-size-fits-all
approach
without regard to genetic or biologic variations in the patient. Existing
approaches continue to
leave unmet patient need.
100051 The heterogeneity of disease pathogenesis and clinical
course, combined with the
variable response to treatment and its associated side effects, suggests a
targeted therapeutic
approach to treating these diseases is a desirable treatment strategy. Yet
there are very few

[0086] FIG. 8 demonstrates that TL1A drives inflammation and
fibrosis through binding
to DR3.
[0087] FIGS. 9A-9C demonstrates size-exclusion chromatography (SEC)
profiles of
recombinant human TL1A (rhTL I A). Briefly, rhTL1A was labeled with Alexa
fluor 488
(AF488) and spiked into normal human serum (NHS). In FIG. 9A, when injected
alone,
rhTL1A SEC profile shows two peaks on SEC, representing trimeric and monomeric
forms
of TL1A. In FIG. 9B, when rhTL1A is pre-incubated with a control reference
antibody, the
trimeric peak was shifted leftward, indicating a larger complex formation of
the reference
antibody and trimeric rhTL1A. There was no shift in the monomeric peak,
indicating that the
reference antibody only binds to the trimeric rhTL1A. In FIG. 9C, when rhTL1A
is pre-
incubated with A219, both the trimeric and the monomeric rhTL1A peaks were
shifted, thus
indicating that A219 binds both trimeric and monomeric forms of TL A.

4. DESCRIPTION OF THE INVENTION
1001121 TL1A is a cytokine that is secreted by antigen-presenting
cells, T cells, and
endothelial cells. 'TL1A signals through death receptor 3 (DR3), a 'TNF-family
receptor that is
found primarily on T cells, natural killer (NK) and NK-T cells, innate
lymphoid cells (ILC),
fibroblasts, and epithelial cells and potently drives Thl, Th2, Th9 and Th17
responses. In
addition, it is induced in antigen-presenting cells by toll like receptor
(TLR) ligands and FcR
cross-linking and in T cells by T cell receptor (TCR) stimulation.
[00113] FIG. 8 demonstrates how TL1A binding to DR3 independently drives
inflammation and fibrosis. TL1A binding to DR3 on innate and T cells leads to
an early
cytokine response (release of IL-23, IL-113, IL-17, IL-22, TNF-a, IFN-y, IL-
13) that sets the
stage for inflammation, and stimulates innate and adaptive immune response.
For instance,
through binding to DR3, TL1A potentially drives inflammatory Thl and Th17
responses.
Further, binding of TL1A to DR3 on fibroblasts directly activates fibroblasts,
and leads to
collagen disposition and fibrosis independent of inflammation. While levels of
circulating
TL IA are low in healthy subjects, they are elevated in patients suffering
from many auto-
immune diseases, and TL1A has been shown to be upregulated in mucosa and serum
of
patients with IBD. In mice, chronic TL1A expression causes structuring disease
caused by
increased collagen deposition. In dextran sodium sulfate (DSS) and adoptive
transfer mouse
models, when challenged with DSS, TL1A transgenic mice develop more severe
colitis than
wild-type animals, and antibodies against TL1A led to reduced inflammation,
lowered
collagen levels, and reversal of fibrosis, even when treatment was
administered late in the
course of disease, after inflammation and fibrosis has been established
Furthermore, TL1A
polymorphisms have been shown to be associated with susceptibility to IBD and
with disease
severity.
1001141 Fibrosis is a significant clinical phenotype exhibited by
IBD patients. Seventy

WO 2022/178159
PCT/US2022/016841
percent of Crohn's disease (CD) patients develop stricture/perforation, and
stricture is the
leading indication for surgery in CD. Unfortunately, anti-inflammatory agent
use over the
past decade has not materially changed the rate of structuring disease or need
for surgery.
Further, in ulcerative colitis (UC), subclinical fibrosis has significant
implications on patient
symptoms. For instance, subclinical fibrosis could contribute to symptoms of
diarrhea,
abdominal pain, urgency, and incontinence. Subclinical fibrosis is also the
potential
explanation for persistent symptoms after resolution of inflammation. In
addition, a
Cleveland Clinic study of 89 consecutive colectomy specimens revealed
submucosal fibrosis
in 100% of the specimens. Thus, treatment of fibrosis constitutes an unmet
need in IBD.
1001151 The potential for TL1A as a therapeutic target in
intestinal fibrosis has been
demonstrated in a study evaluating the effect of anti-TL1A antibodies in mouse
models of
IBD. In these studies, two mouse models of chronic colitis were utilized:
adoptive T cell
transfer and chronic DSS. In both models, a neutralizing TL1A monoclonal
antibody (mAb)
or an isotype control antibody was administered two times per week in mice (T
cell transfer
n=14; DSS n=28) with an established colitis. In both disease models, treatment
with the
TL1A mAb reduced colonic collagen deposition levels back to those seen in
healthy control
mice, suggesting that blocking TL1A signaling not only prevented progression
of colonic
fibrosis, but also reversed established fibrosis to similar levels measured
prior to the onset of
inflammation. This data indicates that intestinal fibrosis mediated by
increased levels of
TL1A may be treated with an anti-TL1A antibody.
1001161 In one aspect, provided herein are humanized monoclonal antibodies
that bind to
both membrane-bound and soluble forms of TL1A with high affinity and
specificity and
block the binding of TL1A to its functional receptor DR3. By targeting both
inflammation
and fibrosis, such antibodies have the potential to improve outcomes for IBD
patients, such as
those with increased TL1A expression.
1001171 The term "and/or" as used in a phrase with a list of members is
intended to include
all members individually and all combination of full or partial list of
members. For example,
a phrase such as "A and/or B" herein is intended to include both A and B; A or
B; A (alone);
and B (alone). Likewise, the term "and/or" as used in a phrase such as "A, B,
and/or C" is
intended to encompass each of the following embodiments: A, B, and C; A, B, or
C; A or C;
A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C
(alone).

generally well understood and/or commonly employed using conventional
methodology by
those skilled in the art, such as, for example, the widely utilized
methodologies described in
Sambrook et al., Molecular Cloning: A Laboratory Manual (3d ed. 2001); Current
Protocols
in Molecular Biology (Ausubel et a/. eds., 2003); Therapeutic Monoclonal
Antibodies: From
Bench to Clinic (An ed. 2009); Monoclonal Antibodies: Methods and Protocols

ed. 2010).
4.2 Anti-TL1A Antibodies
[00119] TT,1A exists in both monomeric and trimeric form in vivo
and in vitro The
disclosure provides that although the trimeric form is the biologically active
form that can
bind to the physiological receptor, death receptor 3 ("DR3") and trigger TL1A
mediated
signaling (e.g. Zhan, C et al., Structure 19: 162-171(2011)), monomeric TL1A
accounts for a
large fraction of the TL1A pool in a subject. By one of the inventors'
estimates, the
monomeric TL1A can be 60% of the total TL1A in the circulating blood. The term
"total
TL1A" refers to both monomeric and trimeric TL1A. The disclosure further
provides that,
despite monomeric TL being biologically inactive, anti-TL1A antibodies binding
to both
monomeric and trimeric TL1A provide advantages over antibodies binding to only
trimeric
TL1A. As provided herein and further demonstrated in Section 5, such
advantages include
more efficient reduction of the TL1A concentration in a diseased tissue in a
subject including
the concentration trimeric TL1A in the diseased tissue, more efficient
reduction of the TL1A
concentration in the blood in a subject including the concentration trimeric
TL1A in the
blood, more sustained reduction of TL concentration (including trimeric
TLIA
concentration) in a diseased tissue in a subject, and/or more sustained
reduction of TL1A
concentration (including trimeric TL1A concentration) in the blood in a
subject.
[00120] In one aspect, provided herein are antibodies or antigen binding
fragments thereof
that bind to tumor necrosis factor-like protein lA ("TL1A," and such antibody
or antigen
binding fragment thereof, "anti-TL1A antibody or antigen binding fragment" or
"anti-TL1A
antibody(ies)" in the specification for simplicity), wherein the antibodies or
antigen binding
fragments bind to both monomeric TL1A and trimeric TL1A. Further embodiments
of the
anti-TL1A antibodies, including embodiments with exemplary CDRs, framework
sequences,
constant region sequences, Fc mutations, variable regions, Fc regions, and
other properties
are further provided in this Section (Section 4.2). Assays for screening,
testing, and
validating the anti-TL1A antibodies are provided in Section 4.3. Methods for
generating,
improving, mutating, cloning, expressing, and isolating the anti-TL1A
antibodies are
- 28 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
provided in Section 4.4. Pharmaceutical compositions for the anti-TL1A
antibodies are
described and provided in Section 4.5. Methods of using the anti-TL1A
antibodies are
provided in Section 4.6. Further specific and validated embodiments for the
anti-TL1A
antibodies and the methods of using the same are provided in Section 5. As
such, the
disclosure provides the various combinations of the anti-TL1A antibodies, the
pharmaceutical
compositions of such anti-TL1A antibodies, the methods of generating the anti-
TL1A
antibodies, the methods of assaying the anti-TL1A antibodies, and the methods
of using the
anti-TL1A antibodies for treatment.
1001211 In one embodiment of the various anti-TL1A antibodies or antigen
binding
fragments thereof provided herein, the antibody or antigen binding fragment
blocks binding
of TL1A to Death Receptor 3 ("DR3"). In another embodiment, the antibody or
antigen
binding fragment blocks the binding of trimeric TL1A to DR3. In a further
embodiment, the
antibody or antigen binding fragment blocks the signaling DR3 signaling
mediated by TL1A
In yet another embodiment, the antibody or antigen binding fragment blocks the
increase of
IFNy secretion by various immune cells. In a specific embodiment, the antibody
or antigen
binding fragment blocks the increase of IFNy secretion by peripheral blood
mononuclear
cells, including various B cells, T cells, natural killer cells, and/or
macrophages.
1001221 As described herein, the disclosure provides anti-TL1A antibodies or
antigen
binding fragments for binding both monomeric and trimeric TL1A. Therefore, in
one
embodiment of the various anti-TL1A antibodies or antigen binding fragments
thereof
provided herein, binding affinity of the antibody or antigen binding fragment
to monomeric
TL1A as measured by dissociation equilibrium constant (K-monomer) is
comparable to binding
affinity of the antibody or antigen binding fragment to trimeric TL1A as
measured by
dissociation equilibrium constant (Kp_tiimer). Such KD_monomer and/or KDtrim,
can be
determined via any of the methods known and practice by a skilled artisan in
the field and via
any of the applicable assays and methods described herein, including in this
Section (Section
4.2) and Section 5.
1001231 The terms "binds" or "binding" refer to an interaction between
molecules
including, for example, to form a complex. Interactions can be, for example,
non-covalent
interactions including hydrogen bonds, ionic bonds, hydrophobic interactions,
and/or van der
Waals interactions. A complex can also include the binding of two or more
molecules held
together by covalent or non-covalent bonds, interactions, or forces. The
strength of the total
non-covalent interactions between a single antigen-binding site on an antibody
and a single
epitope of a target molecule, such as TL I A, is the affinity of the antibody
or functional
- 29 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
fragment for that epitope. The ratio of dissociation rate (koff) to
association rate (k011) of an
antibody to a monovalent antigen (koff/kon) is the dissociation constant Kip,
which is inversely
related to affinity. The lower the KD value, the higher the affinity of the
antibody. The value
of KD varies for different complexes of antibody and antigen and depends on
both k0n and
koff. The dissociation constant KD for an antibody provided herein can be
determined using
any method provided herein or any other method well known to those skilled in
the art. The
affinity at one binding site does not always reflect the true strength of the
interaction between
an antibody and an antigen. When complex antigens containing multiple,
repeating antigenic
determinants, such as a polyvalent TL IA trimer, come in contact with
antibodies containing
multiple binding sites, the interaction of antibody with antigen at one site
will increase the
probability of a reaction at a second site. The strength of such multiple
interactions between
a multivalent antibody and antigen is called the avidity. The avidity of an
antibody can be a
better measure of its binding capacity than is the affinity of its individual
binding sites.
1001241 "Binding affinity" generally refers to the strength of the sum total
of noncovalent
interactions between a single binding site of a molecule (e.g., a binding
protein such as an
antibody) and its binding partner (e.g, an antigen). Unless indicated
otherwise, as used
herein, "binding affinity" refers to intrinsic binding affinity which reflects
a 1:1 interaction
between members of a binding pair (e.g., antibody and antigen). As described
above, the
affinity of a binding molecule X for its binding partner Y can generally be
represented by the
dissociation constant (KD). Affinity can be measured by common methods known
in the art,
including those described herein. Low-affinity antibodies generally bind
antigen slowly and
tend to dissociate readily, whereas high-affinity antibodies generally bind
antigen faster and
tend to remain bound longer. A variety of methods of measuring binding
affinity are known
in the art, any of which can be used for purposes of the present disclosure.
Specific
illustrative embodiments include the following. In one embodiment, the "KD" or
"KD value"
can be measured by assays known in the art, for example by a binding assay.
The KD can be
measured in a RIA, for example, performed with the Fab version of an antibody
of interest
and its antigen (Chen et al., 1999, J. Mol Biol 293:865-81). The KD or KD
value can also be
measured by using surface plasmon resonance assays by Biacore , using, for
example, a
Biacore TM-2000 or a Biacore TM-3000, or by biolayer interferometry using, for
example,
the OcterQK384 system. An "on-rate" or "rate of association" or "association
rate" or "lc."
can also be determined with the same surface plasmon resonance or biolayer
interferometry
techniques described above using, for example, a Biacore(')TM-2000 or a
BiacoreTM-3000,
or the Octee'QK3 84 system.

1001281 In one aspect, provided herein are antibodies that bind to TL1A. In
some
embodiments, an antibody comprises an antigen-binding fragment that refers to
a portion of
an antibody having antigenic determining variable regions of an antibody.
Examples of
antigen-binding fragments include, but are not limited to Fab, Fab', F(ab')2,
and Fv
fragments, linear antibodies, single chain antibodies, and multi specific
antibodies formed
from antibody fragments. In some embodiments, an antibody refers to an
immunoglobulin
molecule that recognizes and specifically binds to a target, such as a
protein, polypeptide,
peptide, carbohydrate, polynucleotide, lipid, or combinations of the foregoing
through at least
one antigen recognition site within the variable region of the immunoglobulin
molecule. In
some embodiments, an antibody includes intact polyclonal antibodies, intact
monoclonal
antibodies, antibody fragments (such as Fab, Fab', F(ab')2, and Fv fragments),
single chain
Fv (scFv) mutants, a CDR-grafted antibody, multispecific antibodies, chimeric
antibodies,
humanized antibodies, human antibodies, fusion proteins comprising an antigen
determination portion of an antibody, and any other modified immunoglobulin
molecule
comprising an antigen recognition site so long as the antibodies exhibit the
desired biological
activity. An antibody can be of any the five major classes of immunoglobulins:
IgA, IgD,
IE5F, IgG, and IgM, or subclasses (isotypes) thereof (e.g., IgGI, IgG2, IgG3,
IgG4, IgAl and
IgA2), based on the identity of their heavy-chain constant domains referred to
as alpha, delta,
epsilon, gamma, and mu, respectively. The different classes of immunoglobulins
have
different and well-known subunit structures and three-dimensional
configurations. Antibodies
can be naked or conjugated to other molecules such as toxins, radioisotopes,
etc.
1001291 In some embodiments, a humanized antibody refers to forms of non-human
(e.g.,
murine) antibodies having specific immunoglobulin chains, chimeric
immunoglobulins, or
- 32 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
fragments thereof that contain minimal non-human (e.g., murine) sequences. In
a non-
limiting example, a humanized antibody comprises less than about 40% non-human
sequence
in the variable region. In some cases, a humanized antibody comprises less
than about 20%
non-human sequence in a full-length antibody sequence. In a further non-
limiting example, a
humanized antibody comprises less than about 20% non-human sequence in the
framework
region of each of the heavy chain and light chain variable regions. For
instance, the
humanized antibody comprises less than about 20%, 19%, 18%, 17%, 16%, 15%,
14%, 13%,
12%, 11%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, or 1% non-human sequence in the

framework region of each of the heavy chain and light chain variable regions.
As another
example, the humanized antibody comprises about or less than about 15, 14, 13,
12, 11, 10, 9,
8, 7, 6, 5, 4, 3, 2, or 1 non-human sequences in the framework region of each
of the heavy
chain and light chain variable regions. In some cases, humanized antibodies
are human
immunoglobulins in which residues from the complementarity determining region
(CDR) are
replaced by residues from the CDR of a non-human species (e.g., mouse, rat,
rabbit, hamster)
that have the desired specificity, affinity, and capability. These humanized
antibodies may
contain one or more non-human species mutations, e.g., the heavy chain
comprises about 1,
2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15 non-human species mutations
in the framework
region, and the light chain comprises about 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12,13, 14, or 15
non-human species mutations in the framework region. The humanized heavy chain
variable
domain may comprise IGHV1-46*02 framework with no or fewer than about 10,9, 8,
7, 6, 5,
4, 3, 2, or 1 amino acid mutations. The humanized light chain variable domain
may comprise
IGKV3-20 framework with no or fewer than about 10, 9, 8, 7, 6, 5, 4, 3, 2, or
1 amino acid
mutations.
1001301 In some embodiments, chimeric antibodies refer to antibodies
wherein the
sequence of the immunoglobulin molecule is derived from two or more species.
As a non -
limiting example, the variable region of both light and heavy chains
corresponds to the
variable region of antibodies derived from one species of mammals (e.g.,
mouse, rat, rabbit,
etc.) with the desired specificity, affinity, and capability while the
constant regions are
homologous to the sequences in antibodies derived from another (usually human)
to avoid
eliciting an immune response in that species.
1001311 The terms "complementarity determining region," and "CDR," which are
synonymous with "hypervariable region" or "HVR," are known in the art to refer
to non-
contiguous sequences of amino acids within antibody variable regions, which
confer antigen
specificity and/or binding affinity. In general, there are three CDRs in each
heavy chain

PCT/US2022/016841
variable region (CDR-H1, CDR-H2, CDR-H3) and three CDRs in each light chain
variable
region (CDR-L1, CDR-L2, CDR-L3). "Framework regions" and "FR" are known in the
art to
refer to the non-CDR portions of the variable regions of the heavy and light
chains. In
general, there are four FRs in each full-length heavy chain variable region
(FR-H1, FR-H2,
FR-H3, and FR-H4), and four FRs in each full-length light chain variable
region (FR-L1, FR-
L2, FR-L3, and FR-L4). The precise amino acid sequence boundaries of a given
CDR or FR
can be readily determined using any of a number of well-known schemes,
including those
described by Kabat et al. (1991), "Sequences of Proteins of Immunological
Interest," 5th Ed.

[00132] In some embodiments, an antibody that specifically binds to a protein
indicates
that the antibody reacts or associates more frequently, more rapidly, with
greater duration,
with greater affinity, or with some combination of the above to the protein
than with
alternative substances, including unrelated proteins.
[00133] In some embodiments, the terms "polypeptide," "peptide," and "protein"
are used
interchangeably herein to refer to polymers of amino acids of any length. The
polymer may
be linear or branched, it may comprise modified amino acids, and it may be
interrupted by
non-amino acids. The terms also encompass an amino acid polymer that has been
modified
naturally or by intervention; for example, disulfide bond formation,
glycosylation, lipidation,
acetylation, phosphorylation, or any other manipulation or modification, such
as fusion with
another polypeptide and/or conjugation, e.g., with a labeling component. Also
included
within the definition are, for example, polypeptides containing one or more
analogs of an
amino acid (for example, unnatural amino acids, etc.), as well as other
modifications known

polymer. A polynucleotide may be further modified after polymerization, such
as by
conjugation with a labeling component.
[00136] Percent (%) sequence identity with respect to a reference polypeptide
sequence is
the percentage of amino acid residues in a candidate sequence that are
identical with the
amino acid residues in the reference polypeptide sequence, after aligning the
sequences and
introducing gaps, if necessary, to achieve the maximum percent sequence
identity, and not
considering any conservative substitutions as part of the sequence identity.
Alignment for
purposes of determining percent amino acid sequence identity can be achieved
in various
ways that are known for instance, using publicly available computer software
such as
BLAST, BLAST-2, ALIGN or MegaHD) (DNASTAR) software. Appropriate parameters
for
aligning sequences are able to be determined, including algorithms needed to
achieve
maximal alignment over the full length of the sequences being compared. For
purposes
herein, however, % amino acid sequence identity values are generated using the
sequence
comparison computer program ALIGN-2. The ALIGN-2 sequence comparison computer
program was authored by Genentech, Inc., and the source code has been filed
with user
documentation in the U.S. Copyright Office, Washington D.C., 20559, where it
is registered
under U.S. Copyright Registration No. TXU510087. The ALIGN-2 program is
publicly
available from Genentech, Inc., South San Francisco, Calif., or may be
compiled from the
source code. The ALIGN-2 program should be compiled for use on a UNIX
operating
system, including digital UNIX V4.0D. All sequence comparison parameters are
set by the
ALIGN-2 program and do not vary.
[00137] In situations where ALIGN-2 is employed for amino acid sequence
comparisons,
the % amino acid sequence identity of a given amino acid sequence A to, with,
or against a
given amino acid sequence B (which can alternatively be phrased as a given
amino acid
sequence A that has or comprises a certain % amino acid sequence identity to,
with, or
against a given amino acid sequence B) is calculated as follows: 100 times the
fraction X/Y,
where X is the number of amino acid residues scored as identical matches by
the sequence
alignment program ALIGN-2 in that programs alignment of A and B, and where Y
is the
total number of amino acid residues in B. It will be appreciated that where
the length of
amino acid sequence A is not equal to the length of amino acid sequence B, the
% amino acid
sequence identity of A to B will not equal the % amino acid sequence identity
of B to A.
Unless specifically stated otherwise, all % amino acid sequence identity
values used herein
are obtained as described in the immediately preceding paragraph using the
ALIGN-2
computer program.

amount.
For instance, an antibody variable region comprising about 80% identity to a
reference
variable region may comprise 72% to 88% identity to the reference variable
region.

1001781 In some embodiments, antibodies of this disclosure have a reduced
effector
function as compared to a human IgG. Effector function refers to a biological
event resulting
from the interaction of an antibody Fc region with an Fc receptor or ligand.
Non-limiting
effector functions include Clq binding, complement dependent cytotoxicity
(CDC), Fc
receptor binding, antibody-dependent cell-mediated cytotoxicity (ADCC),
antibody -
dependent cellular phagocytosis (ADCP), cytokine secretion, immune complex-
mediated
antigen uptake by antigen presenting cells, down regulation of cell surface
receptors (e.g., B
cell receptor), and B cell activation. In some cases, antibody-dependent cell-
mediated
cytotoxicity (ADCC) refers to a cell-mediated reaction in which nonspecific
cytotoxic cells
expressing Fc receptors (e.g., natural killer cells, neutrophils, macrophages)
recognize bound
antibody on a target cell, subsequently causing lysis of the target cell. In
some cases,
complement dependent cytotoxicity (CDC) refers to ly sing of a target cells in
the presence of
complement, where the complement action pathway is initiated by the binding of
Clq to
antibody bound with the target.
1001791 Some Fc regions have a natural lack of effector function, and some Fc
regions can
comprise mutations that reduce effector functions For instance, IgG4 has low
ADCC and
CDC activities and IgG2 has low ADCC activity.
1001801 The disclosure provides antibodies comprising Fc regions characterized
by
exhibiting ADCC that is reduced by at least about 30%, at least about 40%, at
least about
50%, at least about 60%, at least about 70% or more as compared to an antibody
comprising
a non-variant Fc region, i.e., an antibody with the same sequence identity but
for the
sub stitution(s) that decrease ADCC (such as human IgGl, SEQ ID NO: 320). The
disclosure
provides antibodies comprising Fc regions characterized by exhibiting CDC that
is reduced
by at least about 30%, at least about 40%, at least about 50%, at least about
60%, at least
about 70% or more as compared to an antibody comprising a non-variant Fc
region, i.e., an
antibody with the same sequence identity but for the sub stitution(s) that
decrease CDC (such
as human IgGl, SEQ ID NO: 320). In certain embodiments, the antibodies of this
disclosure
have reduced effector function as compared with human IgG1 . In certain
embodiments,
antibodies herein have no detectable ADCC activity. In certain embodiments,
the reduction
and/or abatement of ADCC activity may be attributed to the reduced affinity
antibodies of the
invention exhibit for Fc ligands and/or receptors. In certain embodiments,
antibodies herein
exhibit no detectable CDC activities. In some embodiments, the reduction
and/or abatement
of CDC activity may be attributed to the reduced affinity antibodies of the
invention exhibit
for Fc ligands and/or receptors. Measurement of effector function may be
performed as
- 79 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
described in Example 3.
[00181] In some embodiments, antibodies comprising Fe regions described herein
exhibit
decreased affinities to Clq relative to an unmodified antibody (e.g, human
IgG1 having SEQ
ID NO: 320). In some embodiments, antibodies herein exhibit affinities for Clq
receptor that
are at least 2 fold, or at least 3 fold, or at least 5 fold, or at least 7
fold, or at least 10 fold, or
at least 20 fold, or at least 30 fold, or at least 40 fold, or at least 50
fold, or at least 60 fold, or
at least 70 fold, or at least 80 fold, or at least 90 fold, or at least 100
fold, or at least 200 fold
less than an unmodified antibody. In some embodiments, antibodies herein
exhibit affinities
for Clq that are at least 90%, at least 80%, at least 70%, at least 60%, at
least 50%, at least
40%, at least 30%, at least 20%, at least 10%, or at least 5% less than an
unmodified
antibody.
1001821 In some embodiments, the antibodies of this disclosure are variants
that possess
some but not all effector functions, which make it a desirable candidate for
applications in
which the half-life of the antibody in vivo is important yet certain effector
functions (such as
complement and ADCC) are unnecessary or deleterious.
[00183] In vitro and/or in vivo cytotoxicity assays can be conducted to
confirm the
reduction/depletion of CDC and/or ADCC activities. For example, Fe receptor
(FcR) binding
assays can be conducted to ensure that the antibody lacks FcyR binding (hence
likely lacking
ADCC activity) but retains FcRn binding ability. Measurement of effector
function may be
performed as described in Example 3.
1001841 In some embodiments, antibodies are tested for binding to Fey
receptors and
complement Clq by ELISA. In some embodiments, antibodies are tested for the
ability to
activate primary human immune cells in vitro, for example, by assessing their
ability to
induce expression of activation markers.
[00185] In some embodiments, assessment of ADCC activity of an anti-TL1A
antibody
comprises adding the antibody to target cells in combination with immune
effector cells,
which may be activated by the antigen antibody complexes resulting in
cytolysis of the target
cell. Cytolysis may be detected by the release of lab el (e.g. radioactive
substrates, fluorescent
dyes or natural intracellular proteins) from the lysed cells. Useful effector
cells for such
assays include peripheral blood mononuclear cells (PBMC) and Natural Killer
(NK) cells.
Specific examples of in vitro ADCC assays are described in Wisecarver et al.,
1985 79:277-
282; Bruggemann et al., 1987, J Exp Med 166:1351-1361; Wilkinson et al., 2001,
J Immunol
Methods 258:183-191; Patel et al., 1995 J Immunol Methods 184:29-38.
Alternatively, or
additionally, ADCC activity of the antibody of interest may be assessed in
vivo, e.g., in an

expressed as intact Ig in 293 cells using small-scale (3 mL, 6-well culture
plates)
transfections, (2) the expression level of the antibody was assessed in the
culture supernatant
96-120 hours after transfection using an antibody quantitation ET,TSA, (3) the
binding of the
supernatant antibody variants to human TL1A was assessed by ELISA, (4) the
antibody was
purified in a single step using Protein A and (5) the material was analyzed by
analytical SEC
to assess monomer/aggregate content. This approach enabled identification of
variants that
expressed well, preserved binding to TL1A, and displayed high monomer content.

1002281 Further provided herein are assays for quantifying antibody
expression. For
example, as described in Example 2.
1002291 Further provided herein are assays for quantifying immunogenicity of
an
antibody.

any
method known in the art. The immunoassays which can be used include, but are
not limited
to, competitive and non-competitive assay systems using techniques such as

4.4 Methods of Generating Antibodies
1002311 In various embodiments, monoclonal antibodies are prepared using
methods
known in the art, such as, but not limited to the hybridoma method, where a
host animal is
immunized to elicit the production by lymphocytes of antibodies that will
specifically bind to
an immunizing antigen (Kohler and Milstein (1975) Nature 256:495). Hybridomas
produce
- 98 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
monoclonal antibodies directed specifically against a chosen antigen. The
monoclonal
antibodies are purified from the culture medium or ascites fluid by techniques
known in the
art, when propagated either in vitro or in vivo.
1002321 In some embodiments, monoclonal antibodies are made using recombinant
DNA
methods. The polynucleotides encoding a monoclonal antibody are isolated from
mature B-
cells or hybridoma cells. The isolated polynucleotides encoding the heavy and
light chains
are then cloned into suitable expression vectors, which when transfected into
host cells (e.g.,
E. coil cells, simian COS cells, Chinese hamster ovary (CHO) cells, or myeloma
cells)
generate monoclonal antibodies. The polynucleotide(s) encoding a monoclonal
antibody can
further be modified in a number of different manners using recombinant DNA
technology to
generate alternative antibodies.
1002331 In various embodiments, a chimeric antibody, a molecule in which
different
portions are derived from different animal species, such as those having a
variable region
derived from a murine monoclonal antibody and a human immunoglobulin constant
region
(e.g., humanized antibodies) can be generated.
1002341 In some embodiments, the anti-TL1 A monoclonal antibody is a humanized

antibody, to reduce antigenicity and HAMA (human anti-mouse antibody)
responses when
administered to a human subject. Humanized antibodies can be produced using
various
techniques known in the art. For example, an antibody is humanized by (1)
determining the
nucleotide and predicted amino acid sequence of the starting antibody light
and heavy
variable domains; (2) designing the humanized antibody, e.g., deciding which
antibody
framework region to use during the humanizing process; (3) the actual
humanizing
methodologies/techniques; and (4) the transfection and expression of the
humanized
antibody. In various embodiments, a humanized antibody can be further
optimized to
decrease potential immunogenicity, while maintaining functional activity, for
therapy in
humans.
1002351 Humanized antibodies can also be made in transgenic mice containing
human
immunoglobulin loci that are capable, upon immunization, of producing the full
repertoire of
human antibodies in the absence of endogenous immunoglobulin production. A
humanized
antibody may also be obtained by a genetic engineering approach that enables
production of
affinity-matured human-like polyclonal antibodies in large animals.
1002361 A fully humanized antibody may be created by first designing a
variable region
amino acid sequence that contains non-human, e.g., rodent-derived CDRs,
embedded in
human-derived framework sequences. The non-human CDRs provide the desired
specificity.
- 99 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
Accordingly, in some cases these residues are included in the design of the
reshaped variable
region essentially unchanged. In some cases, modifications should therefore be
restricted to a
minimum and closely watched for changes in the specificity and affinity of the
antibody. On
the other hand, framework residues in theory can be derived from any human
variable region.
A human framework sequences should be chosen, which is equally suitable for
creating a
reshaped variable region and for retaining antibody affinity, in order to
create a reshaped
antibody which shows an acceptable or an even improved affinity. The human
framework
may be of germline origin, or may be derived from non -germline (e.g., mutated
or affinity
matured) sequences. Genetic engineering techniques well known to those in the
art, for
example, but not limited to, phage display of libraries of human antibodies,
transgenic mice,
human-human hybridoma, hybrid hybridoma, B cell immortalization and cloning,
single-cell
RT¨PCR or HuRAb Technology, may be used to generate a humanized antibody with
a
hybrid DNA sequence containing a human framework and a non-human CDR.
1002371 In certain embodiments, the anti-TL1A antibody is a human antibody.
Human
antibodies can be directly prepared using various techniques known in the art.
Immortalized
human B lymphocytes immunized in vitro or isolated from an immunized in divi
dual that
produce an antibody directed against a target antigen can be generated.
1002381
Chimeric, humanized and human antibodies may be produced by recombinant
expression. Recombinant polynucleotide constructs typically include an
expression control
sequence operably linked to the coding sequences of antibody chains, including
naturally
associated or heterologous promoter regions. In certain embodiments, it may be
desirable to
generate amino acid sequence variants of these humanized antibodies,
particularly where
these improve the binding affinity or other biological properties of the
antibody.
1002391 In certain embodiments, an antibody fragment is used to treat and/or
ameliorate
lBD. Various techniques are known for the production of antibody fragments.
Generally,
these fragments are derived via proteolytic digestion of intact antibodies
(for example
Morimoto et al., 1993, Journal of Biochemical and Biophysical Methods 24:107-
117;
Brennan et al., 1985, Science, 229:81). Fab, Fv, and scFv antibody fragments
can all be
expressed in and secreted from E. coli or other host cells, thus allowing the
production of
large amounts of these fragments. Other techniques for the production of
antibody fragments
will be apparent to the skilled practitioner.
1002401 According to the present disclosure, techniques can be adapted for the
production
of single-chain antibodies specific to TL1A. In addition, methods can be
adapted for the
construction of Fab expression libraries to allow rapid and effective
identification of
- 100 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
monoclonal Fab fragments with the desired specificity for TL1A, or
derivatives, fragments,
analogs or homologs thereof. Antibody fragments may be produced by techniques
in the art
including, but not limited to: (a) a F(ab')2 fragment produced by pepsin
digestion of an
antibody molecule; (b) a Fab fragment generated by reducing the disulfide
bridges of an
F(ab')2 fragment, (c) a Fab fragment generated by the treatment of the
antibody molecule
with papain and a reducing agent, and (d) Fv fragments.
1002411 Also provided herein are modified antibodies comprising any type of
variable
region that provides for the association of the antibody with TL1A. Those
skilled in the art
will appreciate that the modified antibodies may comprise antibodies (e.g.,
full-length
antibodies or immunoreactive fragments thereof) in which at least a fraction
of one or more
of the constant region domains has been deleted or otherwise altered so as to
provide desired
biochemical characteristics such as decreasing TL1A. In certain embodiments,
the variable
regions in both the heavy and light chains are altered by at least partial
replacement of one or
more CDRs and, if necessary, by partial framework region replacement and
sequence
changing. In some embodiments, the replaced CDRs may be derived from an
antibody of the
same class, subclass, from an antibody of a different class, for instance,
from an antibody
from a different species and/or a combination thereof. In some embodiments,
the constant
region of the modified antibodies will comprise a human constant region.
Modifications to
the constant region compatible with this disclosure comprise additions,
deletions or
substitutions of one or more amino acids in one or more domains.
1002421 In various embodiments, the expression of an antibody or antigen-
binding
fragment thereof as described herein can occur in either prokaryotic or
eukaryotic cells.
Suitable hosts include bacterial or eukaryotic hosts, including yeast,
insects, fungi, bird and
mammalian cells either in vivo, or in situ, or host cells of mammalian,
insect, bird or yeast
origin. The mammalian cell or tissue can be of human, primate, hamster,
rabbit, rodent, cow,
pig, sheep, horse, goat, dog or cat origin, but any other mammalian cell may
be used. In other
embodiments, the antibody or antigen-fragment thereof as described herein may
be
transfected into the host.
1002431 In some embodiments, the expression vectors are transfected into the
recipient cell
line for the production of the chimeric, humanized, or composite human
antibodies described
herein. In various embodiments, mammalian cells can be useful as hosts for the
production of
antibody proteins, which can include, but are not limited to cells of
fibroblast origin, such as
Vero (ATCC CRL 81) or CHO-Kt (ATCC CRL 61) cells, HeLa cells and L cells.
Exemplary
eukaryotic cells that can be used to express polypeptides include, but are not
limited to, COS

cells, including COS 7 cells; 293 cells, including 293-6E cells; CHO cells,
including CHO¨
S and DG44 cells; PER.C6Tm cells (Crucell); and NSO cells. In some
embodiments, a
particular eukaryotic host cell is selected based on its ability to make
desired post-
translational modifications to the heavy chains and/or light chains.
[00244] A number of suitable host cell lines capable of secreting intact
heterologous
proteins have been developed in the art, and include, but are not limited to
CHO cell lines,
various COS cell lines, HeLa cells, L cells and multiple myeloma cell lines.
[00245] An expression vector carrying a chimeric, humanized, or composite
human
antibody construct, antibody or antigen-binding fragment thereof as described
herein can be
introduced into an appropriate host cell by any of a variety of suitable
means, depending on
the type of cellular host including, but not limited to transformation,
transfection, lipofection,
conjugation, electroporation, direct microinjection, and microprojectile
bombardment, as
known to one of ordinary skill in the art. Expression vectors for these cells
can include
expression control sequences, such as an origin of replication sites, a
promoter, an enhancer
and necessary processing information sites, such as ribosome binding sites,
RNA splice sites,
polyadenylation sites, and transcriptional terminator sequences.
[00246] In various embodiments, yeast can also be utilized as hosts for the
production of
the antibody molecules or peptides described herein. In various other
embodiments, bacterial
strains can also be utilized as hosts for the production of the antibody
molecules or peptides
described herein. Examples of bacterial strains include, but are not limited
to E. coil, Bacillus
species, enterobacteria, and various Pseudomonas species.
[00247] In some embodiments, one or more antibodies or antigen-binding
fragments
thereof as described herein can be produced in vivo in an animal that has been
engineered
(transgenic) or transfected with one or more nucleic acid molecules encoding
the
polypeptides, according to any suitable method. For production of transgenic
animals,
transgenes can be microinjected into fertilized oocytes, or can be
incorporated into the
genome of embryonic stem cells, and the nuclei of such cells transferred into
enudeated
oocytes. Once expressed, antibodies can be purified according to standard
procedures of the
art, including HPLC purification, column chromatography, gel electrophoresis
and the like
(see generally, Scopes, Protein Purification (Springer-Verlag, NY, 1982)).
[00248] Once expressed in the host, the whole antibodies, antibody-
fragments (e.g.,
individual light and heavy chains), or other immunoglobulin forms of the
present disclosure
can be recovered and purified by known techniques, e.g., immunoabsorption or
immunoaffinity chromatography, chromatographic methods such as HPLC (high

performance liquid chromatography), ammonium sulfate precipitation, gel
electrophoresis, or
any combination of these. See generally, Scopes, PROTEIN PURIF. (Springer-
Verlag, NY,
1982). Substantially pure immunoglobulins of at least about 90% to 95%
homogeneity are
advantageous, as are those with 98% to 99% or more homogeneity, particularly
for
pharmaceutical uses. Once purified, partially or to homogeneity as desired, a
humanized or
composite human antibody can then be used therapeutically or in developing and
performing
assay procedures, immunofluorescent stainings, etc. See generally, Vols. I &
II Immunol.
Meth. (Lefkovits & Pernis, eds., Acad. Press, NY, 1979 and 1981).
[00249] Various embodiments provide for a genetic construct comprising a
nucleic acid
encoding an anti-TL I A antibody or fragment provided herein. Genetic
constructs of the
antibody can be in the form of expression cassettes, which can be suitable for
expression of
the encoded anti-TL1A antibody or fragment. The genetic construct may be
introduced into a
host cell with or without being incorporated in a vector. For example, the
genetic construct
can be incorporated within a liposome or a virus particle. Alternatively, a
purified nucleic
acid molecule can be inserted directly into a host cell by methods known in
the art. The
genetic construct can be introduced directly into cells of a host subject by
transfection,
infection, electroporation, cell fusion, protoplast fusion, microinjection or
ballistic
bombardment.
[00250] Various embodiments provide a recombinant vector comprising the
genetic
construct of an antibody provided herein. The recombinant vector can be a
plasmid, cosmid
or phage. The recombinant vectors can include other functional elements; for
example, a
suitable promoter to initiate gene expression.
[00251] Various embodiments provide a host cell comprising a genetic construct
and/or
recombinant vector described herein.
[00252] Various host systems are also advantageously employed to express
recombinant
protein. Examples of suitable mammalian host cell lines include the COS-7
lines of monkey
kidney cells, and other cell lines capable of expressing an appropriate vector
including, for
example, L cells, C127, 3 T3, Chinese hamster ovary (CHO), HeLa and BHK cell
lines.
Mammalian expression vectors can comprise non-transcribed elements such as an
origin of
replication, a suitable promoter and enhancer linked to the gene to be
expressed, and other 5'
or 3' flanking non-transcribed sequences, and 5' or 3' non-translated
sequences, such as
necessary ribosome binding sites, a polyadenylation site, splice donor and
acceptor sites, and
transcriptional termination sequences.
[00253] The proteins produced by a transformed host can be purified according
to any
- 103 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
suitable method. Such standard methods include chromatography (e.g., ion
exchange, affinity
and sizing column chromatography), centrifugation, differential solubility, or
by any other
standard technique for protein purification. Affinity tags such as
hexahistidine (SEQ ID NO:
391), maltose binding domain, influenza coat sequence and glutathione-S-
transferase can be
attached to the protein to allow easy purification by passage over an
appropriate affinity
column. Isolated proteins can also be physically characterized using such
techniques as
proteolysis, nuclear magnetic resonance and x-ray crystallography. Recombinant
protein
produced in bacterial culture can be isolated.
1002541 One of skill will recognize that individual substitutions,
deletions or additions to a
nucleic acid, peptide, polypeptide, or protein sequence which alters a single
amino acid or a
small percentage of amino acids in the encoded sequence is a "conservatively
modified
variant" where the alteration results in the substitution of an amino acid
with a chemically
similar amino acid and retain the ability to specifically bind the target
antigen. Such
conservatively modified variants are in addition to and do not exclude
polymorphic variants,
interspecies homologs, and alleles consistent with the disclosure.
1002551 A given amino acid can be replaced by a residue having
similar physiochemical
characteristics, e.g., substituting one aliphatic residue for another (such as
He, Val, Leu, or
Ala for one another), or substitution of one polar residue for another (such
as between Lys
and Arg; Glu and Asp; or Gln and Asn). Other such conservative substitutions,
e.g.,
substitutions of entire regions having similar hydrophobicity characteristics,
are well known.
Polypeptides comprising conservative amino acid substitutions can be tested in
any one of the
assays described herein to confirm that a desired activity, e.g. antigen-
binding activity and
specificity of a native or reference polypeptide is retained.
1002561 Particular conservative substitutions include, for example;
Ala into Gly or into
Ser; Arg into Lys; Asn into Gin or into H is; Asp into Glu; Cy s into Ser; Gin
into Asn; Glu
into Asp; Gly into Ala or into Pro; His into Asn or into Gin; lie into Leu or
into Val; Leu into
lie or into Val; Lys into Arg, into Gin or into Glu; Met into Leu, into Tyr or
into lie; Phe into
Met, into Leu or into Tyr; Ser into Thr; Thr into Ser; Trp into Tyr; Tyr into
Trp; and/or Phe
into Val, into lie or into Leu.
1002571 In some embodiments, the antibody and/or antigen-binding fragment
thereof
described herein can be a variant of a sequence described herein, e.g., a
conservative
substitution variant of an antibody polypeptide. In some embodiments, the
variant is a
conservatively modified variant. A variant may refer to a polypeptide
substantially
homologous to a native or reference polypeptide, but which has an amino acid
sequence
- 104 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
different from that of the native or reference polypeptide because of one or a
plurality of
deletions, insertions or substitutions. Variant polypeptide-encoding DNA
sequences
encompass sequences that comprise one or more additions, deletions, or
substitutions of
nucleotides when compared to a native or reference DNA sequence, but that
encode a variant
protein or fragment thereof that retains activity, e.g., antigen-specific
binding activity for the
relevant target polypeptide.
[00258] Alterations of the native amino acid sequence can be accomplished by
any of a
number of techniques known to one of skill in the art. Mutations can be
introduced at
particular loci or by oligonucleotide-directed site-specific mutagenesis
procedures.
Techniques for making such alterations are very well established and include,
for example,
those disclosed by Walder et al. (Gene 42: 133, 1986); Bauer et al. (Gene
37:73, 1985); Craik
(BioTechniques, January 1985, 12-19); Smith et al. (Genetic Engineering:
Principles and
Methods, Plenum Press, 1981).
[00259] Nucleic acid molecules encoding amino acid sequence variants of
antibodies are
prepared by a variety of methods known in the art. These methods include, but
are not limited
to, preparation by oligonucleotide-mediated (or site-directed) mutagenesis,
PCR mutagenesis,
and cassette mutagenesis of an earlier prepared variant or a non-variant
version of the
antibody. A nucleic acid sequence encoding at least one antibody, portion or
polypeptide as
described herein can be recombined with vector DNA in accordance with
conventional
techniques, including but not limited to, blunt-ended or staggered-ended
termini for ligation
and restriction enzyme digestion. Techniques for such manipulations are
disclosed, e.g., by
Maniatis et al., Molecular Cloning, Lab. Manual (Cold Spring Harbor Lab.
Press, NY, 1982
and 1989), and can be used to construct nucleic acid sequences which encode a
monoclonal
antibody molecule or antigen-binding region.
[00260] In some embodiments, a nucleic acid encoding an antibody or antigen-
binding
fragment thereof as described herein is comprised by a vector. In some of the
aspects
described herein, a nucleic acid sequence encoding an antibody or antigen-
binding fragment
thereof as described herein, or any module thereof, is operably linked to a
vector. The term
"vector," as used herein, refers to a nucleic acid construct designed for
delivery to a host cell
or for transfer between different host cells. As used herein, a vector can be
viral or non-viral.
The term "vector" encompasses any genetic element that is capable of
replication when
associated with the proper control elements and that can transfer gene
sequences to cells. A
vector can include, but is not limited to, a cloning vector, an expression
vector, a plasmid,
phage, transposon, cosmid, chromosome, virus, virion, etc.

1002611 As used herein, the term "expression vector" refers to a vector that
directs
expression of an RNA or polypeptide from sequences linked to transcriptional
regulatory
sequences on the vector. The term "expression" refers to the cellular
processes involved in
producing RNA and proteins and as appropriate, secreting proteins, including
where
applicable, but not limited to, for example, transcription, transcript
processing, translation and
protein folding, modification and processing. "Expression products" include
RNA transcribed
from a gene, and polypeptides obtained by translation of mRNA transcribed from
a gene. The
term "gene" means the nucleic acid sequence which is transcribed (DNA) to RNA
in vitro or
in vivo when operably linked to appropriate regulatory sequences. The gene may
or may not
include regions preceding and following the coding region, e.g., 5'
untranslated (5 'UTR) or
"leader" sequences and 3' UTR or "trailer" sequences, as well as intervening
sequences
(introns) between individual coding segments (exons).
1002621 As used herein, the term "viral vector" refers to a nucleic
acid vector construct
that includes at least one element of viral origin and has the capacity to be
packaged into a
viral vector particle. The viral vector can contain the nucleic acid encoding
an antibody or
antigen-binding portion thereof as described herein in place of non-essential
viral genes. The
vector and/or particle may be utilized for the purpose of transferring any
nucleic acids into
cells either in vitro or in vivo. Numerous forms of viral vectors are known in
the art.
1002631 By "recombinant vector," it is meant that the vector includes a
heterologous
nucleic acid sequence, or "transgene" that is capable of expression in vivo.

therapeutics suitable for injection and/or administration are important to
realizing full
therapeutic potential. However, administration is generally restricted by
volume, for instance,
when the therapeutic is delivered subcutaneously. This, in turn, elucidates
the importance
developing of high concentration antibody formulations of greater than, for
example in some
cases, 100 mg/ml. Problems associated with antibody development include high
solution
viscosity and opalescence, which are commonly encountered during the
development of high-
concentration (e.g., greater than 100 mg/ml). Both viscosity and opalescence
impact antibody
developability broadly, affecting manufacturability, stability, and delivery.
High solution
viscosities (e.g., greater than 30 mPa-s) cause limiting back-pressures in
ultrafiltration/diafiltration during the antibody concentration unit
operation. Similarly,
viscous antibody solutions also result in forbidding or incompatible injection
forces when
administering via injection, including via patient friendly autoinjectors. In
effect, solution
viscosity can be a determining factor for the maximum antibody dose possible
via injection.
Solution opalescence in therapeutic antibodies can be equally problematic as
opalescence can
indicate predisposition for liquid-liquid phase separation, precipitation, or
aggregation.
Further difficulty may occur with blinding of subcutaneous placebo.
1002791 The anti-TL1A antibodies provided herein demonstrate advantageous
viscosity
and aggregation properties at high antibody concentrations (e.g., greater than
about 100, 125,
150, 160, 170, 180, 190, or 200 mg/mL). Notably, anti-TL1A antibodies provided
herein are
characterized by low viscosity (e.g., less than 20 mPa-s) and low aggregation
(e.g., less than
5% high molecular weight species) at high concentrations (FIGS. 3A-3C).
1002801 For example, in some embodiments, the anti-T1LA antibody is
characterized by a
viscosity less than about 30, 20, 15, or 10 mPa-s at a concentration greater
than about 100
mg/mL, e.g., about 150 mg/mL to about 300 mg/mL, about 150 mg/mL to about 200
mg/mL,
about 150 mg/mL to about 225 mg/mL, or about 150 mg/mL to about 250 mg/mL. In
some
cases, the antibody comprises a HCDR1 comprising SEQ ID NO: 1, a HCDR2
comprising
SEQ ID NO: 2, a HCDR3 comprising SEQ ID NO: 6, a LCDR1 comprising SEQ ID NO:
10,
a LCDR2 comprising SEQ ID NO: 11, and a LCDR3 comprising SEQ ID NO: 12, and/or

having a heavy chain variable region comprising SEQ ID NO: 104 and a light

4.6 Methods of Treatment
[00302] The disclosure provides that the anti-TL1A antibodies or antigen
binding
fragments and the pharmaceutical compositions thereof provided herein can be
used in a
method to treat an inflammatory disease or condition in a subject by
administering the anti-
TLIA antibodies or antigen binding fragments or the pharmaceutical
compositions thereof
described herein to the subject. More specifically, the anti -TL1 A antibodies
or antigen
binding fragments and the pharmaceutical compositions thereof provided herein
can be used
in a method to treat an inflammatory bowel disease ("IBD") in a subject by
administering the
anti-TL1A antibodies or antigen binding fragments or the pharmaceutical
compositions
thereof described herein to the subject. In various embodiments, IBD is
Crohn's Disease
(CD) and/or ulcerative colitis (UC).
[00303] In one aspect, provided herein is a method of neutralizing monomeric
TL1 A and
trimeric TL1A in a subject comprising (a) administering an effective dose of
anti-TL1A
antibody or antigen binding fragment to the subject, wherein the antibody or
antigen binding
fragment binds to both monomeric TL1A and trimeric TL I A, and wherein the
antibody or
antigen binding fragment blocks interaction of TL1A to DR3. In certain
embodiments, the
subject has IBD. In some embodiments, the concentration of TL1A in a diseased
tissue in the
subject is reduced below the concentration of TL1A in a corresponding tissue
in a control
subject without IBD.
[00304] "Neutralizing" TL1A refers to binding to TL1A in such a way that the
functional
receptor, DR3, can no longer bind to TL and/or signal via the ligation with
TL1A. As
such, an anti-TL1 A antibody that blocks TL1 A binding to DR3 also neutralizes
DR3.
[00305] In another aspect, provided herein is a method of reducing the
concentration of
TL1A in a diseased tissue in a subject with inflammatory bowel disease ("IBD")
comprising
(a) administering an effective dose of anti-TL1A antibody or antigen binding
fragment to the

the subject
below the concentration of TLIA in a corresponding tissue in a control subject
without IBD.
[00306] In yet another aspect, provided herein is a method of treating IBD in
a subject in
need thereof comprising (a) administering an anti-TLIA antibody or antigen
binding
fragment to the subject, wherein the anti-TLIA antibody or antigen binding
fragment is
administer at an effective dose such that the concentration of TL1A in a
diseased tissue in the
subject after step (a) is below the concentration of TLIA in a corresponding
tis sue in a
control subject without MD.
[00307] In a further aspect, provided herein is a method of treating IBD in a
subject in
need thereof comprising (a) administering an anti-TLIA antibody or antigen
binding
fragment to the subject, wherein the anti-TL1A antibody or antigen binding
fragment is
administered at an effective dose such that the concentration of TL1A in a
diseased tissue in
the subject after step (a) is below the concentration of TL1 A in a
corresponding tissue in a
control subject without IBD.

additional steps. In some embodiments of the methods provided herein,
including the
methods provided in this Section (Section 4.6), the methods further comprises
(c) maintaining
TL1A in the diseased tissue in the subject at a concentration below the
concentration of
TL1A in the corresponding tissue in the control subject. In certain
embodiments, the TL1A
in the diseased tissue in the subject is maintained with a maintenance regimen
of the anti-
TL1A antibody or antigen binding fragment. In some specific embodiments, the
TL1A in the
diseased tissue in the subject is maintained in step (c) with a maintenance
regimen of the anti-
TL1A antibody or antigen binding fragment. In certain embodiments, the
maintenance
regimen is administered after the induction regimen.
1003111 The disclosure provides that the induction regimen and the maintenance
regimen
in the methods provided herein, including in this Section (Section 4.6), can
be identical or
different in various aspects. In one embodiment of the methods provided
herein, including in
this Section (Section 4.6), the induction regimen and the maintenance regimen
are identical.
In another embodiment, the induction regimen and the maintenance regimen are
different. In
a further embodiment, the induction regimen comprises doses of the anti-TL1A
antibody or
antigen binding fragment higher than the maintenance regimen. In yet another
embodiment,
the induction regimen comprises doses of the anti-TL1A antibody or antigen
binding
fragment 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9,
9.5,10, 10.5, 11, 11.5, 12,

higher than the maintenance regimen.
1003121 As described above and below, the various methods provided herein can
reduce
the concentration of TL1A in a diseased tissue in the subject below the
concentration of
TL1A in a corresponding tissue in a control subject without IBD.
Alternatively, the various
methods provided herein can reduce the concentration of TL1A in a diseased
tissue in the
subject below a reference TL1A level (e.g. a reference concentration).
Additionally, the
various methods provided herein can reduce the concentration of TL1A in a
diseased tissue in
the subject below the concentration of TL1A in a reference tissue in a control
subject without
IBD. As is already clear from the description above, the diseased tissue in an
IBD patient
overproduces TL1A, which contributes to the cause, phenotypes, and/or symptoms
of the
IBD patient. The various methods provided herein reduces the concentration of
TL1A in the
diseased tissues of the subject below the concentration of TL1A in a
corresponding tissue in a
control subject without IBD, while the diseased tissues (e.g. certain cells in
the diseased
tissues) of the subject are overproducing TL1A. Such reduction of TL1A
concentration in
the diseased tissues of the subject to below (i) a reference TL1A level or
(ii) the concentration
- 154 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
of TL in a corresponding tissue or a reference tissue in a control subject
without IBD,
while the diseased tissue in the subject overproduces TL1A, can also be
referred to as
coverage. For example, a coverage of or covering 100 fold overproduction of
TL1A means
that TL1A concentration in the diseased tissues of the subject is reduced to
below the
concentration of TL in a corresponding tissue or a reference tissue in
a control subject
without IBD, while the diseased tissue overproduces TL up to 100 fold
comparing to the
corresponding tissue or the reference tissue in a control subject without IBD.

1003291 The disclosure provides that there is advantage of using anti-TL1A
antibody or
antigen binding fragments that bind to both monomeric TL1A and trimeric TL1A,
as
neutralizing both monomeric and trimeric TL1A can more efficiently reduce the
functional
trimeric TL1A in diseased tissue. For various embodiments of the methods
provided herein,
including in this Section (Section 4.6, for example those of the preceding
paragraphs), the
antibody or antigen binding fragment binds to both monomeric TL1A and trimeric
TL1A. In
some embodiments of the methods provided herein, the anti-TL1A antibody or
antigen
binding fragment blocks binding of TL to DR3. In certain emb odiments of the
methods
provided herein, the anti-TL1A antibody or antigen binding fragment binds to
both
monomeric TL1A and trimeric TL1A and blocks binding of TL1A to DR3.

consisting of colon, small intestine, rectum, cecum, ileum, spleen, a fibrotic
tissue from IBD,
other tissues with MD pathology, and other tissues of IBD pathogenesis. In one

embodiment, the diseased tissues comprise or consist of any seven selected
from the group
consisting of colon, small intestine, rectum, cecum, ileum, spleen, a fibrotic
tissue from MD,
other tissues with IBD pathology, and other tissues of IBD pathogenesis. In
one
embodiment, the diseased tissues comprise or consist of any eight selected
from the group
consisting of colon, small intestine, rectum, cecum, ileum, spleen, a fibrotic
tissue from IBD,
other tissues with IBD pathology, and other tissues of IBD pathogenesis. In
one
embodiment, the diseased tissues comprise or consist of all nine selected from
the group
consisting of colon, small intestine, rectum, cecum, ileum, spleen, a fibrotic
tissue from IBD,
other tissues with IBD pathology, and other tissues of IBD pathogenesis. For

of colon, small
intestine, rectum, cecum, ileum, spleen, a fibrotic tissue from IBD, other
tissues with IBD
pathology, and other tissues of IBD pathogenesis.
[00333] The tissues with MD pathology refers to tissues that have manifested
changes
caused by IBD. Such manifested changes for IBD pathology can be changes in
gene or
protein expression profile (e.g. higher TL1A expression and/or IFNy
expression), histology
changes (e.g. changes in the organization and arrangements of the various cell
types (such as
damages to layers of epithelial cells), changes in the amount or ratio of cell
various cells
types (such as loss of certain cells or over-amplification of some cells),
and/or occurrence of
cell types not normally seen in the tissue (such as infiltration of m on
ocytes in the tissue)).
[00334] The tissues of MD pathogenesis refers to tissues that have manifested
changes
that will cause or contribute to the development of IBD. Such manifested
changes of IBD
pathogenesis can be changes in gene or protein expression profile (e.g. higher
TL1A
expression and/or IFNy expression), changes in the transportation of proteins
or cells (e.g.
increased secretion of TL1A and/or IFN7 or increased migration of monocyte to
other tissues
of MD pathology), and/or other changes that can cause inflammation in the
tissues of IBD
pathology. The disclosure provides that the tissues of IBD pathogenesis and
the tissues with
IBD pathology are not mutually exclusive. Thus certain tissues of IBD
pathogenesis can also
be tissues with IBD pathology and some tissues with IBD pathology can also be
tissues of
MD pathogenesis.

of colon, tissue close to colon, or tissue whose TL1A level correlates with
that in colon.
Alternatively, the corresponding tissue provided herein for the various
methods for
determining the fold overproduction of TL1A in the diseased tissue can be a
reference tissue
in a control subject without IBD. Additionally, the corresponding tissue
provided herein for
the various methods for determining the fold overproduction of TL1A in the
diseased tissue
can be a reference tissue that is not affected by the IBD in the same diseased
subject. Such
reference tissues are not necessarily the same as the diseased tissue, as long
as the TL1A
concentration in such reference tissue reflects the physiological or basal
level of TL1A
production as further described in the paragraph b elow, Such reference
tissues in a control
subject can be colon, small intestine, rectum, cecum, spleen, ileum, and/or a
tissue (or tissues)
without IBD pathology or abnormal TL1A expression. In one embodiment, the
corresponding tissue or reference tissue in the control subject comprises or
consists of colon.
In one embodiment, the corresponding tissue or reference tissue in the control

including in this
Section (Section 4.6), the fold overproduction of TL in the diseased tissue
can be
determined over a reference level of TL1A instead of over the TL1A level in
the
corresponding tissue in a control subject without IBD. Such reference level of
TL1A can be
a specific concentration, a specific unit of TL1A protein, and/or a specific
proxy
measurement of TL1 A.
1003361 As used herein, the TL1A concentration in the corresponding tissue or
the
reference tissue used for comparing with a diseased tissue for the TL1A over-
production
refers to the TL concentration in such corresponding tissue or
reference tissue at the
physiological or basal level of TL1A production under normal healthy
conditions, i.e. without
IBD or other disease or conditions (e.g. inflammatory or immunodeficient
conditions) that
increases or suppresses TL1A production. In other words, the corresponding
tissue or the
reference tissue used herein refer to normal healthy tissues without pathology
or stimuli that
result in abnormal TL1A production. Such physiological or basal level of TL1A
can be the
average of TL
concentrations in the corresponding tissue or the reference tissue during a
time period, if the TL1A concentration fluctuates with the normal healthy
physiological
activity of such tissue during the time period. In some embodiments, the
period of time used
to average the TL1A concentration can be, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11,
12, 13, 14, 15, 16,

1003601 Methods disclosed herein provide methods of treating an inflammatory
disease or
condition in a subject by administering an anti-TL1A antibody described herein
to the
subject. In example embodiments, the inflammatory disease or condition is
inflammatory
bowel disease. In various embodiments, IBD is Crohn's Disease (CD) and/or
ulcerative
colitis (UC). In some embodiments, the IBD patient presents with fibrosis. In
some
embodiments, the IBD is a severe form of IBD. In some embodiments, the IBD is
a moderate
to severe form of IBD. In some embodiments, the IBD is a moderate form of IBD.
In various
other embodiments, the subject is determined to have an increased TL1A
expression. In some
embodiments, the administration of a therapeutically effective amount of an
anti-TL1A
antibody causes a decrease in TL1A in the subject treated. In example
embodiments, the anti-
TL1A antibody comprises any one of the anti-TL1A antibody embodiments provided
herein.
In some embodiments, the anti-TL1A antibody comprises antibody A, B, C, D, E,
F, G, H, I,
A2, B2, C2, D2, E2, F2, G2, H2, or 12. In some embodiments, the anti-TL1A
antibody
comprises any one of the antibodies of Table 1. As a non-limiting example, the
anti-TL1A
antibody comprises antibody A219.
1003611 In some embodiments, methods comprise treating patients with an anti-
TL1A
antibody comprising higher levels of TL1A as compared to patients who do not
have a
disease or condition herein. In some embodiments, methods comprise treating
patients with
an anti-TL1A antibody comprising higher levels of DR3 as compared to patients
who do not
have a disease or condition herein. For instance, the patients who do not have

1003621 The anti-TL1A antibodies described herein may substantially improve
outcomes
for IBD patients who are predisposed to increased TL1A expression. As an
example, the
patients are selected for treatment with an anti-TL1A antibody herein based on
increased
expression of TL1A in the patient as compared to a reference level (e.g., from
a subject who
does not have IBD). The patients may be selected for increased TL1A expression
as
determined by a genotyping assay to determine the presence of a genotype
associated with
increased TL1A expression. TL1A and nucleic acids encoding TL1A (Tumor
Necrosis Factor
Ligand Superfamily Member 15 (77VFSF15)) are provided as set forth by Entrez
Gene: 9966;
UniProtKB: 095150.
1003631 In some embodiments, a subject refers to any animal, including, but

species, e.g., chicken, emu, ostrich, and fish, e.g., trout, catfish and
salmon. In various
embodiments, a subject can be one who has been previously diagnosed with or
identified as
suffering from or having a condition in need of treatment. In certain
embodiments, the subject
is a human. In various embodiments, the subject previously diagnosed with or
identified as
suffering from or having a condition may or may not have undergone treatment
for a
condition. In some embodiments, a subject can also be one who has not been
previously
diagnosed as having a condition (i.e., a subject who exhibits one or more risk
factors fora
condition). A "subject in need" of treatment for a particular condition can be
a subject having
that condition, diagnosed as having that condition, or at risk of developing
that condition. In
some embodiments, the subject is a "patient," that has been diagnosed with a
disease or
condition described herein. In some instances, the subject is suffering from a
symptom
related to a disease or condition disclosed herein (e.g., abdominal pain,
cramping, diarrhea,
rectal bleeding, fever, weight loss, fatigue, loss of appetite, dehydration,
and malnutrition,
anemia, or ulcers).
[00364] In some embodiments, the term "therapeutically effective amount"
refers to an
amount of an antibody effective to "treat" a disease or disorder in a subject
or mammal. In
some cases, therapeutically effective amount of the drug reduces the severity
of symptoms of
the disease or disorder. In some instances, the disease or disorder comprises
inflammatory
bowel disease (IBD), Crohn's disease (CD), or ulcerative colitis (UC). In some
instances, the
IBD, CD, and/or UC are severe or medically refractory forms of the IBD, CD,
and/or UC
Non-limiting examples of symptoms of IBD, CD, and/or UC include, but are not
limited to,
diarrhea, fever, fatigue, abdominal pain, abdominal cramping, inflammation,
ulceration,
nausea, vomiting, bleeding, blood in stool, reduced appetite, and weight loss.
[00365] In some embodiments, the terms, "treat" or "treating" as used herein
refer to both
therapeutic treatment and prophylactic or preventative measures (e.g., disease
progression),
wherein the object is to prevent or slow down (lessen)the targeted pathologic
condition.
Therapeutic treatment includes alleviating the condition and alleviating
symptoms of the
condition. In some aspects provided herein, subjects in need of treatment
include those
already with a disease or condition, as well as those susceptible to develop
the disease or
condition. The disease or condition may comprise an inflammatory disease or
condition.
[00366] The pharmaceutical compositions may be delivered in a therapeutically
effective
- 205 -
CA 03207817 2023- 8-8

PCT/US2022/016841
amount. The precise therapeutically effective amount is that amount of the
composition that
will yield the most effective results in terms of efficacy of treatment in a
given subject. This
amount will vary depending upon a variety of factors, including but not
limited to the
characteristics of therapeutic compound (including activity, pharmacokinetics,

pharmacodynamics, and bioavailability), the physiological condition of the
subject (including
age, sex, disease type and stage, general physical condition, responsiveness
to a given dosage,
and type of medication), the nature of the pharmaceutically acceptable carrier
or carriers in
the formulation, and the route of administration. One skilled in the clinical
and
pharmacological arts will be able to determine a therapeutically effective
amount through
routine experimentation, for instance, by monitoring a subject's response to
administration of
a compound and adjusting the dosage accordingly. For additional guidance, see
Remington:
The Science and Practice ofPharmacy (Gennaro ed. 20th edition, Williams &
Wilkins PA,
USA) (2000).
1003671 For the treatment of the disease, the appropriate dosage of an
antibody depends on
the type of disease to be treated, the severity and course of the disease, the
responsiveness of
the disease, whether the antibody is administered for therapeutic or
preventative purposes,
previous therapy, and patient's clinical history. The dosage can also be
adjusted by the
individual physician in the event of any complication and at the discretion of
the treating
physician. The administering physician can determine optimum dosages, dosing
methodologies and repetition rates. The TL1A antibody can be administered one
time or over
a series of treatments lasting from several days to several months, or until a
cure is effected or
a diminution of the disease state is achieved (e.g, treatment or amelioration
of IBD
symptoms). The duration of treatment depends upon the subject's clinical
progress and
responsiveness to therapy. In certain embodiments, dosage is from 0.01 pg to
100 mg per kg
of body weight, and can be given once or more daily, weekly, monthly or
yearly.
1003681 In one aspect, a method of treating an inflammatory disease or
condition
comprises administering to a subject an anti-TL1A antibody. In some
embodiments, the
subject is administered a dose of up to about 1000 mg. In some embodiments,

1003921 The following examples are illustrative of the embodiments described
herein and
are not to be interpreted as limiting the scope of this disclosure. To the
extent that specific
materials are mentioned, it is merely for purposes of illustration and is not

exercise of inventive capacity and without departing from the scope of this
disclosure.
Example 1: Design of humanized anti-TL1A antibodies
1003931 Two different strategies were employed to identify humanized variants
that
express well in mammalian cells, preserve TL1A binding, and display high
monomeric
content.
1003941 The first strategy utilized a previously humanized variant, termed
ASX, that
-218 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
displays high monomeric content (98%) and expresses well (30 ug/mL in small-
scale
transient cultures) as a template for additional mutagenesis. However, ASX
contains a
significant number of murine framework residues, eight heavy chain residues
and 7 light
chain residues, that may pose an immunogenicity risk. The ASX heavy and light
chain
templates were used to systematically mutate murine framework residues to
human residues
corresponding to the most closely related human germline framework. The goal
of this
strategy was to reduce the total number of murine framework residues while
preserving the
favorable expression and solubility characteristics of ASX. Because ASX
contained 15
murine framework residues there were 2^15 (32,768) distinct variants
(restricting each
position to either the murine or the human residue) that could be made and
tested.
[00395] The second strategy utilized a previously humanized variant, termed
c34, that
expresses well (17 ug/mL in small-scale transient cultures) and contains CDRs
optimized for
binding within a fully human germline framework, as a template for additional
mutagenesis.
Large-scale expression of c34 unexpectedly resulted in a sub -optimal
monomeric content
(55-60%). The c34 heavy and light chain templates were used to systematically
mutate
certain framework residues to murine residues corresponding to the original
murine antibody
framework. The goal of this strategy was to improve the solubility of c34
(monomeric
content) through the introduction of as few murine framework residues as
possible
(minimizing potential immunogenicity risks) while preserving the favorable
expression
characteristics of c34.
[00396] For both strategies, the initial approach was to scan differing
framework residues,
one at a time, and express and characterize the variants. Thus, human
framework residues
were introduced into variant ASX where it differed from c34 and conversely,
murine
framework mutations were introduced into variant c34 where it differed from A
SX. The
initial scan identified certain framework and CDR residues that had minimal
impact on the
characteristics displayed by the template antibody while other mutations had a
more dramatic
impact, favorable in some cases and unfavorable in others. The information
gained from the
positional scan was subsequently used in an iterative and combinatorial
fashion, to identify
multiple variants with favorable characteristics. Importantly, by applying a
stepwise, iterative
and combinatorial approach the beneficial variants were identified without
necessitating the
expression and characterization of 32,768 distinct variants.
[00397] In certain cases, mutation of the first residue of the heavy chain
from glutamine to
aspartic acid or glutamic acid was evaluated, alone or in combination with
other mutations.
[00398] In addition, for both strategies certain CDR residues were also
mutated to
-219 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
determine the impact on expression and solubility. For example, a limited
number of
mutations in HCDR2, HCDR3 and LCDR3 were examined. Similar to the approach
used
with frameworks, the mutations were predominantly restricted to the original
murine CDR
residue or mutations that were previously identified as enhancing binding
affinity.
1003991 Finally, for both strategies "shuffling" of heavy and light chains was
used.
Specifically, certain human light chains containing few murine framework
residues and
having a favorable impact on expression of antibody with higher monomeric
content were
identified early in the process and these were paired with various engineered
heavy chains in
order to accelerate the process of identifying suitable variants.
1004001 Examples of certain designed antibodies are shown in Table 1.

[00401] As used herein, reference to A(number), refers to an antibody of this
table. For
instance, Al5 used herein refers to Al 5 in Table 1.
Example 2: Generation and characterization of humanized anti-TL1A antibodies
[00402] Humanized anti-TL1A antibodies designed in Example 1 were prepared and

characterized.
[00403] Cloning of humanized antibodies
[00404] DNA encoding leader sequence and the heavy and light chain variable
regions of
humanized variants of interest was cloned into pFusel-hIgGl-Fcl (InvivoGen)
and pFuse2-
CLig-hk (InvivoGen), respectively. Two distinct humanized heavy chain
templates, termed
ASX-HC and c34-HC, and four distinct humanized light chain templates, termed
ASX-LC,
cH3-1, c34-LC, cXL3-13-LC and cXL3-15-LC were all cloned.
[00405] In order to introduce mutations into the templates, the QuickChange
Site Directed
Mutagenesis Kit (Agilent, cat. #200518) was used per manufacturer's
directions. Briefly,
mutagenesis was performed using miniprep double-stranded plasmid DNA, two
synthetic
oligonucleotides primers containing the desired mutation, PfuTurbog DNA
polymerase and a
temperature cycler. Following temperature cycling, the product was treated
with Dpn I. The
nicked vector DNA containing the mutation(s) of interest was used to transform
bacteria.
Subsequently, colonies were picked, the DNA was sequenced to confirm
mutagenesis and
was subsequently used for transfection of mammalian FreeStyle 293 -F cells.
[00406] Antibody expression
[00407] Small-scale (3 mL, 6-well) expression of variants in Free
Style 293-F cells was
performed in the following manner One or two days prior to transfection cells
were passaged
so that the density would be >1 x 106 cells/mL on the day of the transfection.
Typically, this
meant passaging at 6-7 x 105 cells/mL one day prior or 4 x 105 cells/mL two
days prior.
Transfections were only performed with cell viability >90%. On the day of the
transfection
Opti-MEM media was warmed to 37 C and cells were resuspended to 1.1 x 106
cells/mL,
using 3.3 x 106 cells per 3 mL transfection. A total of 3 pig DNA was used for
each

WO 2022/178159
PCT/US2022/016841
transfection. Briefly, the transfections used heavy and light chain plasmid at
a heavy
chain:light chain ratio of 1:3. For 3 mL transfections, 4 pi,L, 293fectin was
added to 96 [IL
Opti-MEM, combined with 100 H.1_, DNA mixture, and incubated at 25 C for 20-30
minutes.
Subsequently, this mixture was added dropwise to 2.8 InL cells and the plate
was transferred
to an incubator and placed on a rotating platform at 175 rpm for up to 120
hours. After 96-
120 hours, transfection supernatants were collected by centrifuging the
transfected cells and
supernatant at 1200 rpm for 5 mm. The supernatant was transferred to a clean
tube and
centrifuged again at 3900 rpm for 10 min to remove any remaining cell debris.
The
supernatant was filtered through a 0.45 mm PES syringe filter and stored at 4
C until the next
step.
1004081 Quantitation of antibody expression
[00409] Antibody expression was quantitated by ELISA. Briefly, a Corning
Costar 3366
96-well round bottom high bind plate was coated with 50 mL anti-kappa (2
[tg/mL) in PBS
overnight at 4 C. The plate was washed 3x with PBS-0.05% Tween 20 (PBS-T) and
was
blocked with 100 [IL 1% BSA/PBS for 1 h at 25 C The block was removed, and
culture
supernatant diluted 5-fold was added and serially diluted 2-fold across the
plate. Every plate
also contained an IgG standard diluted serially 3-fold beginning at 1 gg/mL.
Samples were
incubated for 1 h at 25 C, the plate was washed three times with PBS-T, and 50
anti-Fc
HRP secondary (Southern Biotech #2048-05), diluted 1:4000 in BSA/PBS was added
for 1 h
at 25 C. The plate was washed three times with PBS-T and developed for up to
15 min
following the addition of 501AL Ultra TMB ELISA substrate (Thermo #34028). The
reaction
was terminated by the addition of 50 [it 2 N H2504 and the A450 nm was
measured.
Antibody expression levels obtained from 3 mL scale transfections are shown in
Table 2.

[00410] Antibody binding to human TL1A
[00411] Antibody binding to human TL1A (Fitzgerald #30R-AT070) was quantitated
by
ELISA. Briefly, a Corning Costar 3366 96-well round bottom high bind plate was
coated
with 50 !AL TL1A (1 mg/mL) in PBS overnight at 4 C. The plate was washed 3x
with PBS-
0.05% Tween 20 (PBS-T) and was blocked with 100 tL 1% BSA/PBS for 1 hat 25 C.
The
block was removed, and culture supernatant diluted 5-fold was added and
serially diluted 2 -
fold across the plate. Samples were incubated for 1 h at 25 C, the plate was
washed three
times with PBS-T, and 50 tL anti-Fc 1-1RP secondary, diluted 1:4000 in BSA/PBS
was added
for 1 h at 25 C. The plate was washed three times with PBS-T and developed for
up to 15
min following the addition of 50 jut Ultra TMEI ELISA substrate. The reaction
was
terminated by the addition of 50 [iL 2 N H2SO4 and the A450 nm was measured.
The
antibody affinities, as determined by ELISA titration against human TL1A using
unpurified
culture supernatants, is shown in Table 2.
[00412] Purification of antibodies
[00413] Antibodies were purified from culture supernatants in a single step
using
Dynabeads Protein A (ThermoFisher Scientific, cat. #10002D). First, culture
supernatants
were concentrated per manufacturer's instructions using an Amicon Ultra-4
Centrifugal Filter
Unit (30,000 MWCO; MilliporeSigma, cat. #C7719). The Dynabeads were
resuspended by
gentle vortexing and 100 viL were transferred to an Eppendorf tube. Using a
magnet to retain
the beads, the storage buffer was removed, and the beads were washed with 0.5
mL of 20
mM sodium phosphate, 150 mMNaC1, pH 7.4 (EB, Equilibration Buffer). A total of
up to 24
1.1,g of IgG from culture supernatant was added to the beads and mixed gently
until the beads
were resuspended. When necessary, antibody supernatants were diluted with EB.
The tubes
were placed sideways on a shaking platform and mixed for 10 min at 25 C at 500
rpm.
Subsequently, the beads were collected at the bottom of the tube using a
microfuge at 10,000
rpm for 30 sec. Using a magnet to retain the beads, the supernatant was
removed. The beads
were washed once with 0.5 mL of 20 mM sodium phosphate, 500 mM NaCl, pH 7.4
followed
by another wash with 50 mM sodium phosphate, pH 6Ø The beads were collected
at the
bottom of the tube using a microfuge at 10,000 rpm for 30 sec. Purified
antibody was eluted
from the beads using 20 1.11_, 50 mM sodium acetate, pH 3.5 with gentle mixing
for 2 min at
25 C. Using a magnet to retain the beads, the eluate was transferred to a
fresh tube containing
1.1 lit 1 M Tris, pH 8.5 to neutralize the pH of the sample. This sample was
then centrifuged
at 10,000 rpm for 2 min and transferred to a fresh tube to ensure removal of
residual

Dynabeads. The concentration of the purified sample was determined using a
DeNovix DS-
11 Spectrophotometer/Fluorometer, buffer blank, and a mass extinction
coefficient of 13.70
at 280 nm for a 1% IgG solution.
1004141 Size exclusion chromatography
1004151 The antibodies were analyzed by size exclusion chromatography (SEC) to

determine percent monomer and identify any large molecular weight aggregate
contaminant
species. A total volume of 15 L of protein A purified antibodies at a
concentration of 0.1¨ 1
p,g/iaL were analyzed using a Waters SEC column (Acquity UPLC BEH SEC, 200 A,
1.7 pm,
4.6 x 150 mm) on a Shimadzu UPLC instrument at a flow rate of 0.2 mL/min and a
column
oven temperature of 30 C. Standard PBS was used as the mobile phase and
absorbance at
280 nm was used to monitor protein elution. For some antibody clones tested
that
demonstrated non-symmetrical elution profiles, PBS buffer supplemented with
350 mMNaC1
at pH 6.0 was utilized to reduced non-specific interactions with the column
matrix. The
percent main peak (monomer) value was calculated using the Shimadzu software.
Representative sample profiles are shown in FIGS. IA-C. The monomeric content
of purified
antibody variants is shown in Table 2.
Example 3: Design of humanized anti-TL1A antibodies with reduced effector
function
1004161 In certain cases, it might be beneficial to reduce the
potential effector function of
the antibodies. Multiple strategies to diminish effector function have been
described,
including point mutations to ablate FcyR and Clq binding, cross-subclass Fc
designs to
eliminate FcyR and Clq binding, and glycoengineering to ablate FcyR and Clq
binding.
Representative examples are highlighted in Table 3.

[00417] In order to express antibodies with abrogated effector function, the
light chain
variable regions of the antibodies disclosed in Example 2 and Table 1 are
cloned with a
kappa light chain constant region, while the heavy chain variable regions are
cloned with a
modified IgG1 heavy chain backbone, or a modified IgG2 backbone, or a modified
IgG4
backbone, or an unmodified IgG2 or IgG4 backbone, such as those disclosed in
Table 3,
Table 13, Table 9B, or elsewhere.
[00418] The impact of the various Fc engineering approaches on CDC activity
can be
assessed using Clq binding and C3 fixation assays. Purified antibodies are
diluted in PBS
and serial dilutions are plated on a microtiter plate for 12-18h at 4 C. The
plates are blocked
with 5% gelatin/PBS containing 1% (v/v) Tween-20 for lh at 25 C. Subsequently,
the plates
are incubated with 10% (v/v) human sera in PBS and Clq binding is detected
using 1:500
dilution of HRP-conjugated rabbit anti-Clq (Bioss Inc.) in PBS containing 1%
(v/v) Tween-
20. To test C3 fixation, a 1:1000 dilution of rabbit anti C3 (abeam) is used
followed by a
1:2000 dilution of HRP-conjugated chicken anti-rabbit IgG (abeam). The plates
are
developed as described for antibody quantitation assays in Example 1. EC50
values are

calculated by fitting the data to a log (agonist) vs. response-variable slope
(four parameter)
model using GraphPad Prism (Sunnyvale, CA).
[00419] Additionally, the variants may be characterized for the binding of
isolated Clq.
MaxiSorp 384-well plates (Thermo Scientific, Nunc) are coated with serially
diluted
antibodies in 50 mM carbonate buffer, pH 9.6 (coat buffer), for 12-18h at 4 C.
Plates are
washed with phosphate buffered saline (PBS) containing 0.05% polysorb ate 20,
pH 7.4 and
blocked with PBS containing 0.5% BSA, 0.05% polysorb ate 20, 15 ppm Proclin
and 10%
Blocker Casein (Thermo Scientific), pH 7.4. After 1-hour incubation at 25 C,
plates are
washed. Human Clq (Quidel, San Diego, CA) in the same buffer is added and
incubated for
1.5 hour. Bound Clq is detected by adding 20 ng/mL biotinylated mouse anti-
mouse Clq
(Hycult biotech; cross reacting with human Clq) for 1.5 hour followed by
horseradish
peroxidase (HRP)-conjugated streptavidin (GE Healthcare Life Sciences) for 1
hour. To
check for coating efficiency, some coated wells receive buffer only for the
first two
incubation steps and receive goat anti-human Fab'2-HRP when the wells used for
measuring
Clq binding received streptavidin-HRP. Plates are washed after each incubation
step.
Peroxidase activity is detected with substrate 3,3', 5, 5'-tetram ethyl b enzi
din e (TMB)
(Kirkegaard & Perry Laboratories). The reaction is stopped with 1M phosphoric
acid and
absorbance is measured at 450 nm. Dose-response binding curves are fitted with
a four-
parameter model and EC50 values are calculated using GraphPad Prism
(Sunnyvale, CA).
[00420] The impact of the various Fc engineering approaches on ADCC activity
is
assessed using soluble FcyR receptor binding ELISAs. Soluble human FcyRI,
FcyRII13 and
FcyRIII (binding affinity to both the F158 and V158 polymorphic forms of
FcyRIII is
assessed) are expressed as recombinant fusion proteins with Gly-His6-
glutathione-S-
transferase (GST) at the C-terminus of the extracellular domain of the
receptor. MaxiSorp
384-well plates are coated with 1 g/ml human FcyR in coat buffer. Plates are
washed and
blocked with PBS containing 0.5% BSA, 15 ppm Proclin, pH 7.4. After a 1 h
incubation,
plates are washed and 3-fold serial dilution of antibodies in PBS containing
0.5% BSA,
0.05% poly sorbate 20, 15 ppm Proclin, pH 7.4 is added to the plates and
incubated for 2 h.
For enhanced binding sensitivity due to avidity, immune complexes are formed
using anti-
human antibody. Bound antibody is detected with HRP-conjugated goat anti-human
kappa
(Southern Biotech) using Ultra TMIB substrate as described in Example 1. The
reaction is
terminated and the plate is read as described above. The dose-dependent
binding curve of the
wild type antibody (no Fc modifications) is fitted with GraphPad Prism
(Sunnyvale, CA) four

parameter curve fitting program. The relative affinity of the variant vs. the
wild type is
estimated by dividing the equivalent ng/ml wild type concentration at the
appropriate
concentration.
1004211 In addition, the variants are tested directly in Fc effector
bioassays (Promega)
following manufacturer's directions. These assays include iFyyPdia-H ADCP
IBioassay
(promega cat #C19901), ADCC Reporter Bioassays, EcyRilla F Variant (Promega,
cat
#Ci9798), ADCC Reporter Bioassays, FeyRIIIa V Variant (Prom ega, cat. #G7015).
The
variants are tested both as monomeric Ig and as sin& t immune complexes ( iCs)
by using an
anti-hal-1g antibody to form small ICs.
1004221 A Europium based ADCC assay is performed. Briefly, peripheral blood
lymphocytes (PBLs) are isolated by Ficoll Paque Plus gradient centrifugation.
The PBLs are
collected, washed with RP1VI1640, 10% FCS and resuspended in cell culture
medium. The
cells are diluted to 2.5 x 106 cells/ml. Target cells are labelled with BADTA
(2,2':6',2"-
terpyridine-6,6"-dicarboxylic acid acetoxymethylester): Cells are harvested by
adding
Accutase (Millipore), washed once and diluted to 1 x 106 cells/ml. Next, 2.5
jL BADTA is
added per 1 x 106 cells and incubated for 35 min at 37 C with 5% CO2. After
labelling the
cells are diluted with 10 ml culture medium, centrifuged at 200 x g for 10 min
and
supernatant aspirated. This step is repeated 3X with culture medium/2
mMProbenicid and
the sample is diluted to 1 x 10 cells/ml, centrifuged at 300 x g for 5 min,
supernatant taken
off and 50 IAL pip etted into the wells intended for the background controls.
The final ratio of
effector (PBL) to target cells is 25:1.
1004231 Controls include: (1) Background: the 501xL aliquot, diluted
with 100 pt
medium, (2) Spontaneous lysis: 50 pt of the labelled target cell suspension
plus 100 L
culture medium, incubated 2 h at 37 C, (3) Maximal lysis: 50 L/well of the
labelled target
cell suspension plus 100 L Triton X-100 (0.5% in PBS) incubated 2 h at 37 C,
(4) Lysis
control without antibodies: 50 L/well of the labelled target cell suspension
and 50 IAL
culture medium plus 50 !IL of effector cells incubated 2 h at 37 C, (5) Lysis
control without
effector cells: 50 pi/well of the labelled target cell suspension; add 50 L,
culture medium
plus antibody at highest concentration used and incubate 2 hat 37 C.
At the end of the incubation period the 96 well plate is centrifuged at 100
rpm. 20 pi, of each
supernatant is transferred into an OptiPlate HTRF-96 (Packard) and 200 p,L
Europium
solution is added and incubated for 15 min on a shaker. Fluorescence is
measured as for time
resolved fluorescence and spontaneous release and specific release are
calculated.

1004241 A CDC assay is performed. Briefly, target cells are washed and diluted
to 1 x 105
cells/ml and 100 L/well (104 cells) are added to a 96-well flat bottom
microtiter plate. A
titration curve of the test antibody is created using serial dilutions,
beginning at 1 g/mL.
Antibody is added to the plate, mixed gently, and is then placed at 37nC/5%
CO2 incubator
for 30 min. Next, 25 pL freshly dissolved baby rabbit complement (Cedarlane
CL3441, 1 ml
lyophilized, dilute freshly in 4 ml double distilled water) is added, mixed
gently, and the plate
is incubated at 37 C/5% CO2 incubator for 30 min. After the incubation period
50 L
supernatant is taken off and 100 L Cell Titer Glo. reagent (Promega Corp.) is
added to the
remaining 100 1_, supernatant. The plate is placed on an orbital shaker for 2
min, 100
L/well is transferred into a black luminescence microtiter plate (Costar) and
luminescence is
measured. Controls included: (1) medium control (target cells plus 50 L
medium), (2)
maximal lysis control (target cells plus 501_iL 0.5% Triton X-100), (3)
complement control
(target cells plus 25 L medium plus 25 pt complement).
1004251 As provided and described herein, Fc variants were designed to
diminish effector
function and subsequently tested for the ability to (i) effectively be
purified/manufactured
(Table 11), (ii) reduce antibody-dependent cell-mediated cytotoxicity (ADCC),
and (iii)
reduce complement-dependent cytotoxicity. 'lest articles tested comprise heavy
chain SEQ
ID NOs: 368-380. Heavy chains used were paired with a light chain comprising
SEQ ID NO:
381. ELISA titration profiles and EC5Os were generated against recombinant
TL1A antigen
("EC50", Table 12). Interestingly, Fc mutations did affect purity, as measured
by monomer
content, for select mutations/Fc variants (Table!!, wild-type IgG1 control).
1004261 Reduction of CDC activity
1004271 Test articles were evaluated for CDC activity, compared to negative
control
Human IgG4 isotype control, on TL1A-expressing HEK293 target cells. Rituxan
(anti-CD20)
was used as a positive technical control on CD20-expressing Raji cell. All
test articles were
used at a final top concentration of 10 pg/mL followed by a five-fold dilution
series (7 points
total), in addition to a no treatment control, in triplicate. Cells were
incubated with test
articles for 15 minutes at 37 C, then treated with human complement, at a
final concentration
of 25%, for 3 hours at 37 C, 5% CO2. Following incubation, cells were washed
and
resuspended in Propidium Iodide (P.I.) at a final concentration of 5 1.1g/mL
prior to flow
cytometry analysis. Total cells were examined by flow cytometry during sample
acquisition.
Data were plotted on an XY chart, graphing percentage P.I. positive cells
against the log of
the concentration and fit to a non-linear regression curve. Cell cytotoxicity

7 points total, in addition to no test article control). Treatment conditions
were tested in
triplicate, effector and target cells were co-cultured for 6 hours at 37 C
with 5% CO2. Raji
target cells were used as a positive control, with Rituxan treatment at a top
concentration of
ug/mL, 7-point log dilution series, and no treatment control. Test article 502
treatment
resulted in dose-dependent increase in luciferase reporter gene activity, and
5044 treatment
resulted in increase of reporter activity at the highest tested concentration.
The rest of the test
articles did not induce reporter activity (Table 12).
Example 4: Characterization of potency and species selectivity in whole blood
assay
1004311 The relative potency of a panel of candidate antibodies was first
assessed by
determining the inhibition of interferon gamma release in human blood using
the antibodies
at 1 and 10 nM. All of the antibodies displayed potent activity, with A219
appearing to be
one of the most potent candidates (Table 4).

Example 6: Animal model of colitis
1004341 The efficacy of anti-TL1A antibodies in animal models of colitis is
performed.
Anti-TL1A antibodies are tested in rodent models of acute colitis induced by
intrarectal
administration of di- or tri-nitrobenzenesulfonic acid (D/TNBS) or oxazolone,
and chronic
colitis induced by administration of DSS in drinking water or transfer of
CD45RB T cells.
DNBS and oxazolone induce localized ulceration and inflammation. DSS
administration
induces robust generalized inflammation of the intestinal tract characterized
by erosive
lesions and inflammatory infiltrate. Symptoms of all these models usually
include diarrhea,
occult blood, weight loss and occasionally rectal prolapse. In a prophylactic
model, antibody
treatment begins at the start of administration of the colitis-inducing
compound. In a
therapeutic model, antibody treatment begins several days after commencement
of induction.
The effect of the treatment on weight, stool consistency and occult blood, as
well as
microscopic effects on epithelial integrity and degree of inflammatory
infiltrate is
determined. Daily clinical scoring is performed based on stool consistency and
presence of
occult blood giving a disease activity index (DAI) score.

PCT/US2022/016841
1A (TL1A) with high affinity and specificity and neutralizes TL1A functional
activity in in
vitro and ex vivo cell-based assays. A219 binds to both human and cynomolgus
TL1A with
similar affinity (KD values of 0.06 nM and 0.04 nM, respectively). In
addition, A219 is
specific for TL1A and does not bind to other tumor necrosis factor super
family (TNFSF)
members. A219 blocks human TL1A-induced caspase activation in the TF-1
functional assay
with an 1050 of 0.27 nM. A219 inhibits TL1A-mediated interferon gamma release
from
peripheral blood mononuclear cells (PBMCs) in whole blood from monkeys
administered
doses of >0.056 mg/kg. In addition, a dose-dependent increase in circulating
soluble (sTL1A)
concentrations was observed at all dose levels in these monkeys. This suggests
that systemic
sTL1A levels may be a useful PD marker for target engagement by A219.
1004361 The nonclinical pharmacokinetics (PK) of A219 were characterized in
the monkey
and support the proposed once every other week dosing regimen in humans. The
nonclinical
PK of A219 is as expected for a monoclonal antibody that exhibits target-
mediated drug
disposition (TMDD) at lower doses and linear PK at higher dose levels that
saturate the
target-mediated route of clearance.
1004371 A219 was administered to monkeys once weekly via IV injection for up
to 6
weeks (7 total doses). Most, if not all, of the findings observed after IV
administration of
A219 to monkeys in the 6-week repeat-dose toxicity study were considered to be
secondary
to generation of ADA in response to administration of a foreign protein
(humanized
monoclonal antibody) to immunocompetent animals. Based on electrocardiograms
(ECGs),
daily and detailed weekly clinical observations, and microscopic evaluation of
the relevant
tissues/organs there were no cardiovascular, central nervous system (CNS) or
respiratory
system effects observed in monkeys during 6 weeks of once weekly IV
administration of
A219 at up to 300 mg/kg/week. The clinically relevant no observed adverse
effect level
(NOAEL) in this study was considered to be 300 mg/kg/week (the highest dose
tested). There
was no off-target binding of A219 noted in the tissue cross-reactivity study
with human or
monkey tissues. There was no A219-related cytokine release in the human PBMC
or whole
blood cytokine release assays, nor in monkeys during the 6-week repeat- dose
toxicity study.
A219 did not cause complement-dependent cytotoxicity (CDC) or antibody-
dependent
cellular cytotoxicity (ADCC) of target expressing cells in Fc effector
function assays.
Example 8: Biophysical properties of anti-TLIA antibodies at high
concentrations
1004381 The data for A219 anti-TL1A antibody properties in solution were
analyzed
together using a chemometric method termed partial least squares (PLS).

1004391 The viscosity was measured using an mVROCTM viscometer by Rheosense
with
an A10 chip. The shear rates employed were about 1820 s-1. The viscometer was
temperature controlled using a ThermoCube thermoelectric chiller and the
samples were
delivered using a Hamilton 100 [IL syringe (81060). The accuracy of the
instrument was
verified using neat Isopropyl alcohol and measured at 25 C. Furthermore,
across the
concentration range tested, the percent increase in the HMW fraction as
measured by size
exclusion chromatography ranged from 0% to a 1.3% increase. HMW as used herein
refers
to high molecule weight antibody fraction, e.g., aggregated protein, and which
excludes
monomeric antibody.

1004411 Viscosity
1004421 FIG. 3A depicts the comparison between the predicted and measured
viscosity,
where viscosity is in units of mPa-s. FIGS. 3B-3D demonstrates viscosity as a
function of
antibody concentration and pH. Antibody concentration ranged from greater than
about 125
mg/mL to greater than about 170 mg/mL. pH ranged from less than 5.0 to about
7.5.
Concentration dependence is evident, with very low viscosities (e.g., as
indicated by a

viscosity less than 5 mPa-s or 7mPa-s). All formulations show low viscosities
(< 10 mPa-s),
even at 170 mg/mL. FIG. 3E depicts the effects of pH versus acetate
concentration at an
antibody concentration of 150 mg/mL on viscosity. There is a slight pH
dependence, with
minimal viscosity near pH 6. FIG. 3F shows the effect of sucrose versus NaCl
on viscosity at
a pH pf 5.5 and an antibody concentration of 150 mg/mL. NaCl helps reduce
viscosity, while
HP-b-CD significantly increases viscosity. FIG. 3G depicts the effect of
ArgHC1 versus
Ly sHC1 at a pH of 5.5. ArgHC1 increases viscosity slightly, while LysHC1 has
small effect.
The formulated anti-TL1A antibodies also exhibited low viscosity (less than 16
mPa-s) at 200
mg/ml anti-TL I A.
[00443] Aggregation
[00444] FIG. 4A depicts the PLS1 model for the effect on high molecular weight
(BMW)
aggregates at 2C and 25 C. FIGS. 4B-4E depict the effect of different
parameters on
aggregation. The response surface shows the increase in HMW overtime. FIG. 4B
depicts
the effect of pH versus acetate on aggregation at an antibody concentration of
150 mg/mL. A
lower pH leads to less aggregation (by SEC), using the PLS12 model, including
all
formulations with an increase in HMW species (%) by SEC as the endpoint FIG.
4C depicts
the effect of sucrose versus NaCl concentration on aggregation at a pH of 5.5
and an antibody
concentration of 150 mg/mL. FIG. 4D depicts the effect of ArgHCl versus Ly
sHC1 on
aggregation at a pH of 5.5 and an antibody concentration of 150 mg/mL. FIG. 4E
depicts the
effect of sucrose concentration versus LysHC1 concentration over time at a pH
of 5.5 and an
antibody concentration of 150 mg/mL with 20 mM acetate. Sucrose, sorbitol, and
Lys reduce
aggregation. The formulated anti-TL1A antibodies also exhibited low
aggregation at 200
mg/ml anti-TL1A.
[00445] Loss of Major Peak by Cation Exchange Chromatography CEX
[00446] FIG. 5A depicts the predicted versus measured loss of main peak at 2
weeks and
25 C. FIGS. 5B-5E depict the effect of different parameters on the loss of
main peak. The
response surface indicates the percent loss of the main peak. FIG. 5B depicts
the effect of pH
and protein concentration on the loss of main peak in the CEX profile. The
optimum pH for
reducing loss of main peak by CEX is between 5 and 6. FIG. 5C depicts the
effect of pH and
acetate concentration on the loss of main peak in the CEX profile, at an
antibody
concentration of 150 mg/mL. FIG. 5D depicts the effect of sucrose and NaCl
concentration
on the loss of main peak in the CEX profile, at an antibody concentration of
150 mg/mL and
a pH of 5.5. FIG. 5E depicts the effect of Ly sHC1 and sucrose concentration
on the loss of
main peak in the CEX profile, at an antibody concentration of 150 mg/mL, pH of

exhibited low levels
of loss of main peak at 200 mg/ml anti-TL1A.
Example 9: The effects of Polysorbate 20 or Polysorbate 80 on storage

1004471 After two rounds of formulation screening based on storage stability
at different
temperatures, Round 3 was designed to evaluate the interfacial sensitivity of
two different
base formulations in the presence (and absence) of varying amounts of
polysorbate: PS20 and
PS80. Repeated freeze-thaw (FIT) stress and agitation (Ag) were used as stress
conditions.
Two base formulations of anti-TL I A A219 at -200 mg/ml were evaluated, as

Example 11: Pharmaceutical properties and formulation
[00450] Formulations of anti-TL1A A219 were prepared. An A219 formulation is a
clear
to slightly opalescent, colorless to slightly yellow liquid that is
essentially free of foreign
matter, supplied as 8.4 mL of a 60 mg/mL solution in a 10 mL SCHOTT Fiolax
Type I
Tubular Glass Vial sealed with a West Bromobutyl Rubber Stopper and West Flip-
Off.

[00452] Drug product preparation
[00453] Solutions of A219 may foam. Therefore, shaking or excessive
agitation of vials is
avoided. Additionally, care is taken to ensure the sterility of the prepared
solution, as the drug
product may not contain antimicrobial preservatives or bacteriostatic agents.
A sufficient
excess of drug product may be included in each single use vial to account for
withdrawal
losses.
[00454] Dilution of A219 injection is performed using sterile
disposable latex -free
syringes. An 18 gauge, 1.5 inch sterile needle is used for withdrawal from the
vial. Prior to
IV administration, A219 injection is diluted in a polyvinyl chloride (PVC) IV
bag containing
0.9% Sodium Chloride Injection (normal saline [NS]), using aseptic technique,
to prepare a
dosing solution with a A219 concentrations between 0.01 and 8 mg/mL. The
product is
infused at the protocol-specific dose(s) and rate(s) through a PVC IV solution
infusion set
with a sterile, nonpyrogenic 0.2 j.tm polyethersulfone in line filter. It is
not administered as W
push or bolus injection.

1004561 A219 formulated at 500 mg/vial (60 mg/mL) is stored in a refrigerator
at a
temperature of 2 -8 C (38 -46 F).
Example 12: A219 Binding selectivity
1004571 The predicted TL1A protein sequence in human was compared to the
mouse, rat
and cynomolgus monkey sequences. Mouse, rat and monkey protein sequences were
64%,
66%, and 98% homologous to human TL1A, respectively.
1004581 The binding of A219 to mouse, rat, cynomolgus monkey, and human
recombinant
TL1A protein was assessed in an ELISA. As shown in FIG. 7A, A219 binds to
human and
monkey TL1A with sub-nanomolar IC50 values of 0.33 nM and 0.47 nM,
respectively. In
contrast, A219 did not bind to mouse or rat TL 1A protein.
1004591 A219 binding affinity and kinetics for recombinant human and monkey
TLIA
protein was assessed using surface plasmon resonance (SPR). A219 binds to
human and
cynomolgus TLIA with KD values of 0.06 nM and 0.04 nM, respectively.
1004601 The binding of A219 to membrane-bound 'TL1A was assessed using human

in a dose- dependent manner with an EC50 value of 17.4 nM. There was no
binding to the
parental HEK293 cells.
1004611 ILIA is the only known ligand for its functional receptor DR3. TL1A is
also
capable of binding to Decoy receptor 3 (DcR3), a soluble TNF receptor without
a
transmembrane domain. The binding of A219 to other known ligands of DcR3,
including
TNFSF6 (FasL), TNFSF10 (TRAIL) and TNFSF14 (LIGHT) were assessed by ELISA.
A219
did not bind to these TNF family members when tested at concentrations nearly
1,000-fold
above the EC50 of the respective positive control antibodies.
Example 13: In vitro functional activity of anti-TL1A
1004621 The ability of A219 to prevent DR3 -mediated caspase activation by
either human
or monkey TLIA was assessed in cycloheximide-treated TF-1 cells. TF-1 cells
are human
erythroleukemic cells that natively express DR3, the functional receptor for
TLIA. Human
and cynomolgus TLIA proteins were both capable of binding and activating the
DR3
receptor on human TF-1 cells, resulting in intracellular caspase activation
and apoptosis.
A219 inhibited human and monkey TLIA-induced caspase activation in TF-1 cells
with IC50

values of 0.27 nM and 0.59 nM, respectively.
1004631 PBMCs in whole blood collected from cynomolgus monkeys release IFN-y
when
stimulated with immune complex in the presence of IL-12 and IL-18. This
enhancement of
IFN-y secretion reflects immune complex-driven TL1A production by PBMCs. The
ability of
A219 to inhibit IFN-y release under these conditions was assessed in vitro in
freshly collected
monkey whole blood.
1004641 IFNI, levels were measured in whole blood after stimulation in vitro
with immune
complex in combination with IL-12 and IL-18, and in the presence of increasing

concentrations of A219 (concentration range 0.05 nM to 100 nM). IFN-y release
was
inhibited by A219 in a dose-dependent manner in monkey whole blood. The mean
IC50 and
IC90 values for the inhibition of the IFN-y response were 1.54 nM (289 ng/mL)
and 17.7 nM
(3321 ng/mL), respectively.
Example 14: In vivo pharmacology
1004651 In a single dose PK/PD study with an 11 day follow on period in
monkeys, A219
was administered by IV bolus to 3 animals/group (mixed sexes) at doses of 0
(i.e., 0.56
mg/kg human IgG1 isotype control), 0.0056,0.056 and 0.56 mg/kg. The A219 doses
tested in
the study were selected to result in A219 serum concentrations of
approximately 1-, 10-, or
100-fold of the IC50 based on results from the in vitro monkey whole blood IEN-
y assay.
Blood was collected to assess PK, sTL1A concentrations, and in vitro whole
blood IFN-
release. The effect of A219 on the inhibition of TL1A-mediated IFN-y release
at 0.0056
mg/kg could not be evaluated due to the insufficient increase in IFN-y release
at the pre-dose
baseline. Administration of 0.056 mg/kg or 0.56 mg/kg A219 resulted in nearly
full inhibition
of IFN-y release at 1-hour post-dose, relative to the isotype control. At 264
hours (11 days)
post-dose, inhibition of IFN-y release was less than at 1 hour post-dose but
persisted in the
0.56 mg/kg A219 group. Inhibition of TL1A-mediated IFIN--1 release was dose-
dependent at
doses >0.056 mg/kg where the observed exposure at 0.056 mg/kg was >6.8-fold
above the in
vitro whole blood assay IC50 of 1.54 nM (289 ng/mL).
1004661 Following administration of 0.0056, 0.056 or 0.56 mg/kg A219, the mean

concentration of sTL1 A increased in a dose-dependent manner, by 3.6-, 10.4-,
and 14.4-fold,
respectively, relative to the isotype control antibody at 6 hours post-dose
(FIG. 7B). The
increase in TL1A concentrations across all A219 dose groups was observed at
the earliest
timepoint tested (6 hours post-dose) and was sustained until the last
timepoint (264 hours
post-dose).

[00467] Safety pharmacology
[00468] Cardiovascular, CNS, and respiratory safety pharmacology endpoints
were
incorporated into a 6- week repeat-dose IV toxicity study in monkeys.
[00469] There were no functional effects on the cardiovascular system as
assessed by ECG
measurements in the pre-dose phase and during Weeks 1 and 6 of the dosing
phase, and by
microscopic evaluation of the heart and major blood vessels at 300 mg/kg/week.
There were
no changes related to A219 administration in heart rate, no cardiac rhythm
abnormalities or
qualitative or quantitative ECG changes, and no microscopic findings noted in
the heart that
would have impacted cardiac function.
[00470] There were no functional effects on the CNS based on daily clinical
observations
and detailed weekly examinations that included: observing the animal's
behavior and
movement while approaching the cage, autonomic activity (e.g., lacrimation,
piloerection,
pupil size), changes in posture and reactivity to handling, as well as
presence of clonic or
tonic movements, behavioral /psychological abnormalities, circling, and self-
mutilation at
300 mg/kg/week. There were no microscopic findings in the brain or nervous
system that
would have impacted the CNS function.
[00471] There were no effects on the respiratory system based on daily
clinical
observations of animal respiration and detailed weekly examinations that
included monitoring
for unusual respiratory patterns at 300 mg/kg/week.
[00472] In conclusion, there were no functional cardiovascular, CNS or
respiratory system
findings observed in monkeys during 6 weeks of once weekly IV administration
of A219 at
300 mg/kg/week.
[00473] Systemic pharmacokinetics in animals
[00474] The serum PK and toxicokinetics (TK) of A219 were investigated in the
monkey,
to support dose selection for the pivotal 6-week toxicity study and to aid in
projecting the
appropriate starting dose in humans. IV dosing was used in all in vivo
studies.
[00475] A single IV dose PK/PD study in monkeys was performed to characterize
the PK
profile and the associated PD effects of A2119 at dose levels relevant to
projecting the first-in-
human starting dose. PD results are summarized previously. The PK of A219 was
nonlinear
over the 0.0056,0.056, and 0.56 mg/kg dose range, which is consistent with the
expected
target-mediated drug disposition (TMDD) for a monoclonal antibody to a
membrane-bound
target. AUC values increased in a greater than dose-proportional manner, and
where it could
be estimated, t1/2 increased with increasing dose (Table 20).

1004761 TK and immunogenicity were evaluated in cynomolgus monkeys as part of
a 2 -
dose non-GLP PK/tolerability study and a GLP 6-week repeat-dose toxicity
study.
1004771 In the 2-dose PK study, monkeys (N = 1/sex/group) received 2 doses of
A219 via
IV bolus administration one week apart at dose levels of 30, 100, and 243
mg/kg. Following
the first (Day 1) or second (Day 8) dose, exposure based on mean Cmax
increased in an
approximately dose- proportional manner. Mean AUCO-t values increased in a
dose-
dependent, but not necessarily dose-proportional manner after the first and
second dose.
1904781 In the Gil' 6-week repeat-dose toxicity study, monkeys (N =3-
5/sex/group)
received A219 via IV bolus administration at dose levels of 0, 30, 100, or 300
mg/kg once
weekly for 7 doses. Exposure to A219 was comparable in male and female monkeys

following single and repeat dosing (differences in mean Cmax and AUC values
were less
than 2-fold). A219 exposure increased in an approximately dose-proportional
manner after
single and repeat dosing. Accumulation was observed after repeat once weekly
dosing at all
dose levels (serum exposure after the last dose (Day 42) was approximately 1.5
to 2.3-fold
higher than that observed after the first dose; Table 21).

Example 15: Toxicology
[00479] A219 was assessed in a series of in vitro and vivo toxicity
studies outlined in
Table 22. The IV route of exposure was selected for the in vivo studies. The
weekly dosing
regimen used in the definitive 6-week repeat-dose monkey toxicity study was
selected based
on the half-life of A219 in monkeys and was designed to have a similar or more
intensive
dosing regimen than the clinical dosing regimen.

[00480] The monkey was selected as the pharmacologically relevant nonclinical
species
because of similar TL protein sequence homology and nearly equivalent binding
affinity
of A219 to monkey TL1A, as compared to human TL1A. A219 was also
pharmacologically
active with similar IC50 values after binding monkey or human soluble TL in an
in vitro
cell-based assay. In an in vitro assay using monkey whole blood stimulated to
express TL1A
with subsequently IFNI, release, the addition of A219 inhibited IFNI, release
in a dose-

dependent manner. A similar inhibition of IFN-y release was observed when
blood from
monkeys administered A219 was used in the assay. Binding of A2 19 to mouse or
rat TL1A
was also assessed and A219 did not bind rat or mouse TL1A.
[00481] 2-Dose PK and tolerabilit), study in monkeys
[00482] Tolerability was assessed in a 2-week PK and tolerability study.
Monkeys
(1/sex/group) were administered A219 IV at 30, 100 or 243 mg/kg/week on Days 1
and 8.
A219 was well-tolerated up to the highest dose tested, and the only clinical
signs observed in
A219-treated animals were loose stools in all dose groups at multiple
observation timepoints.
Based on the small numbers of animals and no control group animals, the
relationship of the
loose stools to A219 administration could not be determined. There were no
A219-related
changes in body weight, clinical chemistry, or hematology parameters.
[00483] 6-Week repeat-dose study with a 6-week recovery in monkeys
[00484] A GLP repeat-dose toxicity study of 6 weeks duration (once-weekly
dosing) was
conducted with A219 in monkeys. A219 was administered by IV bolus to male and
female
monkeys (3/sex/group) at doses of 0 (vehicle control), 30, 100, or 300
mg/kg/week (7 doses
total). Additional animals (2/sex/group) at 0 and 300 mg/kg/week were assessed
after a 6-
week recovery period for the reversibility of any A219-related effects.
[00485] A219 was well-tolerated after 6 weeks of administration at doses up to
300
mg/kg/week. Based on these studies, NOAEL is 100 mg/kg/week for males and 30
mg/kg/week for females.
[00486] Human Cytokine Release Assays
[00487] PBMC Assay
[00488] The potential ability of A219 to trigger cytokine release in primary
human
PBMCs derived from 10 normal healthy donors was evaluated in soluble and wet-
coated
formats. A range of A219 concentrations from 0.00002 to 2 mg/mL were
evaluated. A human
IgG4 antibody and untreated samples were used as negative controls; anti-CD3
(OKT3)
antibody was used as positive controls. The levels of IL-2, IL-6, IL-10, TNF,
and INF- were
measured after PBMCs or were cultured with A219 for 24 hours. PBMCs from all
donors
induced IL-2, IL-6, IL-10, TNF, and IFN-y release in response to OKT3
treatment (positive
control). The IL-2 response of Donor 9 was lower but present. The IgG4
negative control
antibody induced no or low IL-2, IL-10, TNF, and IFN-y cytokine release under
any of the
tested conditions. The IgG4 negative control antibody induced IL-6 production
in several
donors, although not as robustly as the positive control treatment. Cytokine
release was either
not observed or only observed at very low levels in untreated samples from all
donors.
- 252 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
[00489] A219 did not induce IL-2 and IFN- release under any of the tested
conditions.
A219 induced low levels of IL-10 and TNF release in some donors, but not above
levels
induced by the IgG4 negative control antibody and/or in untreated samples.
A219 induced IL-
6 release in several donors in the same range of induction as observed with
the IgG4 negative
control and/or in untreated samples in both stimulation formats, but the
responses were not
concentration dependent. Based on historical testing facility data for IL-6
induction, a
variable range of magnitude of responses has been observed for isotype and
other negative
control antibodies, as well as other test articles in subsets of donors that
are often not
concentration dependent. A219, IgG4 treatment-related and untreated PBMC
responses were
lower than the anti-CD3 positive control treatment-related responses.
Therefore, the induction
of IL-6 in this assay was likely not A219-specific but related to variation
that has also been
observed historically in the assay for this cytokine.
[00490] In conclusion, A219 did not induce IL-2, IL-6,
TNF, IFN- specific release
from PBMCs from 10 different donors in wet-coated plate or soluble formats
above that
observed for the IgG4 negative control antibody and/or untreated samples.
[00491] Whole Blood Assay
[00492] The potential ability of A219 to trigger cytokine release in human
whole blood
derived from 10 normal healthy donors was evaluated in soluble and wet-coated
formats. A
range of A219 concentrations from 0.00002 to 2 mg/mL were evaluated. A human
IgG4
antibody and untreated samples were used as negative controls; Staphylococcal
enterotoxin B
(SEB) were used as a positive control. The levels of IL-2, IL-6, IL-10, TNF,
and INF were
measured after whole blood was cultured with A219 for 24 hours.
[00493] Whole blood from all donors induced IL-2, IL-6, IL-10, TNF, and IFN-'y
release
in response to SEB treatment (soluble stimulation format). The IFN- response
of Donors 1,3,
and 8 was lower but present. In whole blood from most donors, the human IgG4
negative
antibody control induced no or low cytokine production under all tested
conditions. Cytokine
release was not observed in untreated whole blood samples of most donors.
Whole blood
from one donor (Donor 7) produced IL-6, IL-10, and TNF-a in response to
several
concentrations of soluble IgG4 negative antibody control. However, the
cytokine levels were
generally at or below the levels observed for the same donor in untreated
samples.
[00494] A219 did not induce any cytokine release under any of the tested
conditions in
nine donors. Stimulation with 0.02 mg/mL of soluble A219 induced release of
low levels of
IL-6, IL-10 and TNF in whole blood from Donor 7. A dose-response relationship
between
A219 concentration and cytokine levels was not observed for this donor, and
the cytokine
- 253 -

WO 2022/178159
PCT/US2022/016841
levels were below those observed with the IgG4 negative control and/or in
untreated samples
from this donor. Therefore, the induction of IL-6, IL-10 and TNF in Donor 7
samples were
likely not A219-specific.
[00495] In conclusion, A219 did not induce IL-2, IL-6, IL-10, TNF, IFN-y
specific release
in whole blood from 10 different donors in wet-coated plate or soluble formats
above that
observed for the 1gG4 negative control antibody and/or untreated samples.
[00496] Fe Effector Function Assays
[00497] The potential for A219 to elicit CDC or ADCC was evaluated in vitro.
A219 was
not expected to elicit CDC or ADCC because the antibody was designed to
abolish effector
functions.
[00498] The ability of A219 to elicit CDC or ADCC on target-expressing
recombinant
human HEK293 TL1A cells and on the HEK293 parental cell line (negative control
cell line)
was evaluated. CDC was assessed by culturing the cells after treatment with a
range of
concentrations (0.0031 to 30,000 ng/mL) of A219 in the presence of human
complement and
analyzing the viability of target cells by flow cytometry. ADCC was assessed
by culturing
labeled target cells, after treatment with a range of concentrations (0.0031
to 30,000 ng/mL)
of A219, with human PBMCs (3 donors). A human IgG4 antibody was used as a
negative
control in both assays.
[00499] Rituxan (anti-CD20 antibody) was used as a positive control in the CDC
assay
with CD20- expressing Raji cells while Darzalex was used in the ADCC assay
with Daudi
target cells.
[00500] A219 treatment did not cause an increase in CDC-mediated cell killing
of
HEK293 TL1A cells or in HEK293 cells as compared to the negative control
antibody.
Rituxan treatment resulted in an expected increase in complement-mediated
lysis of CD20-
expressing Raji cells.
[00501] A219 treatment did not cause an increase in ADCC-mediated cell killing
of
HEK293 TL1A cells or in HEK293 cells as compared to the negative control
antibody.
Darzalex treatment resulted in an expected increase in ADCC cytotoxicity of
Daudi target
cells.
1005021 In conclusion, and as expected, A219 did not elicit CDC or ADCC of
TL1A-
expressing cells in the presence of human complement or PBMCs, respectively.
[00503] Relationship of Findings to Pharmacokinetics
[00504] A219 exposure in monkeys in the 6-week repeat-dose toxicity study, as
defined by
Cmax and AUC, increased with increasing dose over the dose range tested, and
exposure
- 254 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
increased in an approximately dose-proportional manner. There were no apparent
sex-related
differences in exposure. There was no clear correlation of ADA with changes in
A219
exposure. However, it is likely that ADA led to the more rapid decrease in
A219
concentrations at later timepoints that was observed in some of the animals.
Accumulation of
A219 was observed in monkeys after repeated once weekly administration.
1005051 The threshold of serum exposures associated with A219-related findings
from the
6-week repeat-dose monkey toxicity study is shown in Table 23. Safety margins
at each dose
level are presented based on a comparison of A219 AUC values from the 6-week
repeat-dose
monkey toxicity study in comparison to projected human AUC values at the
proposed clinical
starting dose of 5 mg.

1005061 Summary of A219 preclinic al studies
1005071 A219 has sub-nanomolar binding affinity to soluble TL1A and nanomolar
affinity
to membrane-associated TL1A. In in vitro studies, A219 blocked TL1A's ability
to bind and
activate its receptor, DR3. In whole blood, A219 inhibited the TL1A-dependent
IFN-7
response following the ex vivo exposure to immune-complex and a combination of
IL-12 and
IL-18. Additionally, A219 was observed to be highly selective for TL1A with no
detectable
binding to related TNF super family members FAS, LIGHT, or TRAIL.
1005081 The potential toxicity of A219 was assessed in a series of
nonclinical in vitro
assays and in vivo studies in cynomolgus monkeys. The monkey was selected as a

pharmacologically relevant nonclinical species because of similar TL1A protein
sequence
homology and nearly equivalent binding affinity of A219 to monkey TL I A, as
compared to
human. A219 is similarly active in monkey and human in vitro cell-based
assays.
1005091 A219 has been engineered to remove the potential for the mAb to induce
an

immune response. In in vitro assays, A219 treatment did not lead to antibody-
or cell-
mediated cytotoxicity or cytokine release from peripheral blood cells thus
indicating that it
was not provoking an undesired immune response.
[00510] In a tolerability and pharmacokinetic (PK) study, cynomolgus monkeys
(1/sex/group) were administered A219 intravenous (IV) at 30, 100 and 243
mg/kg/week on
Days 1 and 8 and subsequently followed for approximately 11 weeks to assess
systemic
exposure of A219. There were no A219-related clinical observations or changes
in body
weight, clinical chemistry, or hematology parameters. PK measurements
suggested that A219
has along half-life of 5 to 11 days, which is consistent with human IgG1 in
monkeys.
[00511] A GLP study was performed to evaluate the potential toxicity,
including
immunotoxicity, of A219 and associated systemic exposure after six weeks of
once-weekly
dosing (7 total doses) in cynomolgus monkeys. A219 was administered IV (bolus)
to male
and female monkeys (3/sex/group) at doses of 0 (vehicle control), 30, 100, or
300
mg/kg/week. Recovery animals (2/sex/group) were administered 0 or 300
mg/kg/week of
A219. The clinically relevant no observed adverse effect level (NOAEL) in this
study was
determined to be 300 mg/kg/week (the highest dose tested). There were findings
observed
that were secondary to generation of anti-drug antibodies (ADA) in response to

administration of a humanized monoclonal antibody including a single death in
the 30 mg/kg
group and minimal vascular inflammation, which was the only finding that was
considered
adverse. All findings were fully reversible after a 6-week recovery period
except for
perivascular infiltrates, which persisted minimally in only a few tissues at
300 mg/kg/week,
and minimal glomerulopathy noted in one recovery female at 300 mg/kg/week. ADA-
related
findings observed in nonclinical animal toxicity studies with human monoclonal
antibodies
generally are not considered relevant to humans.
[00512] A six-month repeat-dose monkey toxicity study is performed to evaluate
the
potential for chronic dosing in UC and CD.
Example 16: Phase 1 Clinical Trial
1005131 A Phase la clinical trial in normal healthy volunteers has
begun.
1005141 The Phase la clinical trial is a single-center, double-

administration of
A219. The single ascending dose (SAD) phase of the trial consist of 8 subjects
(6 active and 2
placebo) per cohort with up to 6 dose levels. The multiple ascending dose
(MAD) phase of
the trial commences after an equal or higher SAD dose has been studied and

safety and tolerability has been observed. The MAD phase consists of 8
subjects (6 active and
2 placebo) per cohort with up to 5 dose levels. The trial evaluates the
safety, tolerability and
pharmacokinetics of single and multiple doses of A219 via IV administration as
well as the
PK of A219 after single and multiple doses in healthy, ambulatory, non-
smoking, male or
female volunteers aged 18 to 60 years. In addition, the trial determines the
effects of A219 on
pharmacodynamic (PD) markers as well as the exposure-response relationship of
A219 on
PD markers. A synopsis of this study is shown in Table 14.

1005161 Based on the clinical data from SAD cohorts 5,25, 100, 300, and 600 mg
and
MAD cohort 50 mg, A219 PK exhibits target-mediated drug disposition (TMDD) at
lower
doses and linear PK at higher dose levels after the saturation of the target-
mediated route of
clearance.
1005171 Following a single IV dose of A219, median time to maximum
concentration
(Tmax) values ranged from 1.02 to 1.50 hours postdose. Exposure based on mean
Cmax and
AUCot increased in a greater than dose-proportional manner between the 5,25,
and 100 mg
dose levels and in an approximately dose-proportional manner between the 100,
300, and 600
mg dose levels. After repeat once every other week dosing of 50 mg A219,
exposure was
increased relative to Day 1. Mean C. and AUCo-336hr was approximately 1.3
times higher on
Days 15 and 29 compared to Day 1.
Example 17: Human dosing range and safety margins
1005181 A219 is a humanized monoclonal antibody that binds human TL1A. It is
expected
that the ultimate goal of A219 treatment in humans will be to saturate the TL
target in
disease patients to obtain optimal efficacy. A minimum anticipated biological
effect level
(MABEL) approach is not considered appropriate because A219 is an antagonist
rather than
an agonist antibody, and the safety of antagonizing the TL1A pathway has
already been
established in the clinic. The maximum recommended starting dose for A219 was
chosen
based on the predicted pharmacologically active dose (PAD). A219 does not
cross-react with
murine TL1A but binds with approximately equivalent potency to cynomolgus
monkey
TL1A. Therefore, cynomolgus monkey was considered the relevant species for
scaling
nonclinical A219 pharmacokinetics (PK) to human. Additionally, PK data in the
monkey
suggest that A219 exhibits target mediated drug disposition, which leads to
nonlinear PK in
the dose range where the target is not saturated and linear PK in the dose
range where the
target is saturated.
1005191 The nonclinical PK and TK of A219 were characterized in the monkey and

support the proposed once every other week dosing regimen in humans. Estimated
safety
margins for the starting dose of 5 mg and the highest proposed dose for study,
1000 mg,
relative to the GLP safety data from monkeys are shown in Table 24. This table

Example 18: Treatment of IBD with anti-TL1A
1005201 Subjects having inflammatory bowel disease are treated with the anti -
TL1A
antibody A219 using one of the two induction methods of this example:
1005211 Induction method 1: subcutaneous administration of 800 mg of anti-TL1A
on day
1, then weekly at 175-200 mg anti-TL1A for 12 total weeks.
1005221 Induction method 2: intravenous administration of 500 mg of anti-TL1A
every
other week for 12 weeks.
1005231
After the induction period, if the subject is responsive to treatment,
the subj ect is
further treated in a maintenance phase. The maintenance phase comprises
administering 175-
200 mg of anti-TL1A every 2 or 4 weeks.
Example 19: Anti-TL1A antibody binding to both TL1A monomer and TL1A trimer
1005241 To demonstrate that the exemplary anti-TL1A antibody A219 binds to
both TL1A
monomer and TL1A trimer, a peak shifting assay with size exclusion
chromatography was
performed. Briefly, recombinantly produced human TL1A (rhTL1A) was labeled
with Alexa
fluor 488 (AF488) and spiked into normal human serum (NHS). The labeled rhTL1A
in
serum was then injected into a size exclusion column and eluted by monitoring
the AF488
fluorescent signal.
1005251 RhTLIA was observed in at least two peaks for two distinct quaternary
structures,
one for non-covalent trimers and one for monomers (FIG. 9A). The results show
that a
control reference antibody only bound to the trimeric TL1A (FIG. 9B), as only
the trimer
TL1A peak shifted in the presence of the control reference antibody (control
reference
antibody sequence, light chain SEQ ID NO: 382 and heavy chain SEQ ID NO: 383).
In
contrast, A219 bound both TL1A trimers and monomers (FIG. 9C), as both the
monomer and
trimer TL1A peaks shifted in the presence of A219. The results demonstrate
that the
-261 -

WO 2022/178159
PCT/US2022/016841
exemplary anti-TL1A antibody A219 binds to both TL1A monomer and TL1A trimer.
Example 20: PK/PD Models for Determining Effective Dose
[00526] To demonstrate using PK/PD models for determining the effective dose,
an
integrated whole-body physiologically based pharmacokinetic (PBPK) was
established, as
shown in FIG. 10A. The integrated whole body PBPK included a tissue-level
diagram, as
shown in FIG. 10B, to characterize the PK of mAb, ligand, and complex between
mAb and
ligand. The integrated whole-body PBPK model included the following drug-
specific
parameters and/or input: (i) soluble TLIA (sTL I A) is synthesized by immune
cells (e.g.,
dendritic cells) all over the body; (ii) monomeric sTL1A has half-life of 20
minutes, and
trimeric sTL1A has half-life of 1 hour; (iii) affinity parameters (including
the on rate and off
rate) between antibody and sTL1A were fixed to the values measured via SPR
(e.g., as
determined in Example 12); (iv) synthesis rate of sTL1A was adjusted to match
the observed
baseline and PK data; (v) in the diseased individual, the production rate of
sTL1A was
increased by 50-fold in the interstitial space of the intestine. The
parameters and input can be
varied as described herein, including in Section 4.
[00527] The whole-body PBPK model recapitulated the PK observations for A219
and for
TL1A in normal healthy volunteers (NHV). As shown in FIG. 11A, the A219
concentration
predicted by the whole-body PBPK model matched the observed PK for A219 in
NHV.
Furthermore, as shown in FIG. 11B, the TL1A concentration predicted by the
whole-body
PBPK model matched the observed TLIA concentration in NHV during the observed
time
course (assuming constant TL production rate).
[00528] The observed serum concentration of TL1A was almost 10 fold higher
when
A219, an anti-TL1A antibody binding to both monomeric and trimeric TL I A, was
injected,
comparing to that when a control reference antibody that binds to only
trimeric TL1A
antibody was injected in to a subject (FIG. 12A) (control reference antibody
sequence, light
chain SEQ ID NO: 382 and heavy chain SEQ ID NO: 383). Such higher serum TL1A
concentration was recapitulated in the whole-body PBPK, as shown in the curves
in FIG.
12A. Furthermore, the model predicted about 40% monomer TL1A and 60% trimeric
TL I A,
consistent with observations (FIG. 12B). FIG. 12A thus established that
treating patients
with an anti-TL1A antibody that binds to both monomer and trimer TL1 A
sequestered 10
fold higher TL1A into the serum, therefore reduced the TL1A concentration in
diseased
tissues more than an anti-TL1A antibody binding to trimer TL alone. Such
sequestration
of more total TL1A (both monomer and trimer) in serum provides an unexpected
advantage
to a patient who needs to reduce TLIA concentration in diseased tissues, both
in magnitude
- 262 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
and rate of such TL1A reduction.
1005291 The baseline concentration of TL1A in serum from NHV averaged to about
220
ng/mL (162 to 414 ng/mL, 54 subjects, across ¨110 samples). The baseline
concentration of
TL1A in serum from CD subjects averaged to about 273 (158 to 479 ng/mL, 17 CD
subjects).
Thus the difference of serum TL1A concentration between a NHV and a CD patient
is only
modest, confirming the importance of targeting and reducing the concentration
of soluble
TL1A in the diseased tissue. Assuming all TL1A production come from colon, the
model
determined that a 50 fold over-production in colon would reproduce a serum
concentration of
290 ng/mL TL1A, approximating the observations in UC patient (FIG. 12C). Such
big
difference in TL1A in diseased tissue and the modest corresponding difference
in serum
between NHV and UC patients again highlight the importance of targeting and
reducing the
concentration of soluble TL1A in the diseased tissue.
1005301 To further validate and establish the applicability of the whole-body
PBPK model,
the predicted curves of TL1A concentration in serum of NHVs and UC patients
were
compared with the observations from clinical trials. As shown in FIGS. 13A-
13B, the whole-
body PBPK model consistently predicted the observations of total TL1A serum
concentration
in NHVs and UC patients from reported phase land phase II clinical trials
(Banfield C. et al.,
Br J Clin Pharmacol. 2020 Apr;86(4):812-824; and Danese S et al., Clin
Gastroenterol
Hepatol. 2021 Jun 11; S1542-3565(21)00614-5). As shown in FIG. 13C, the whole-
body
PBPK model also predicted tissue interstitial space TL1A levels in the NHV
(normal tissue
production) and UC patients (50 fold increase in local tissue production) in
the absence of
any administration of anti-TL1A antibodies. Thus the fitness of the whole-body
PBPK model
has been validated by the clinical observations.
1005311 Having established the whole-body PBPK model, the whole-body PBPK
model
was used to simulate the concentration of TL1A in diseased tissues and in
serum with various
scenarios of TL1A over-production in the diseased tissues, in the presence or
absence of
various doses of anti-TL1A A219. As shown in FIGS. 14A-14B, the whole-body
PBPK
model simulated TL concentration in intestine for various level of
TL over-production
in intestine (FIG. 14A) and the corresponding serum (plasma) concentration of
TL1A under
these levels of intestinal TL1A over-production, each in the absence of any
administrations of
any anti-TL1A antibodies.
1005321 When anti-TL1A antibody A219 was injected at various dose, the whole-
body
PBPK model simulated the changes of TL concentration in the diseased tissues
over time
(FIGS. 15A-15U). Such simulation can be plotted against the TL1A concentration
in the
- 263 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
corresponding tissue or a reference tissue of a NHV to determine whether the
dose is
sufficient to reduce the TL1A concentration in the diseased tissue below the
TL1A
concentration in the corresponding tissue or a reference tissue of a NHV
(FIGS. 15A-15U).
FIGS 15A-15U also depicts such simulation with various parameters of TL1A over-

production in the diseased intestinal tissues (10x, 25x, 50x, or 100x fold
over-production or
fold increase). As shown in FIGS 15A-15U, the higher the fold over-production,
the higher
the dose or more administrations of the anti-TL1A antibody A219 are needed to
reduce and
keep the TL1A concentration in diseased intestinal tissues below that of the
NHV for the
duration indicated in the figures. More specifically, as shown in FIG. 15R,
administration of
500 mg of the anti-TL1A antibody A219 every other week can cover up to about
125 fold
over-production (fold increase) of TL1A in the intestine of a patient. As
shown in FIG. 15S,
administration of a dose at 1000 mg D1, 500 mg W2, W6, W10, (i.e. 100 mg at
day 1, 500
mg at week 2, 500 mg at week 6, and 500 mg at week 10) of the anti-TL1A
antibody A219
can cover up to about 60 fold over-production (fold increase) of TL1A in the
intestine of a
patient. As shown in FIG. 15T, administration of a dose at 1000 mg D1, 500 mg
W4, W8,
W12, (i.e. 1000 mg at day 1,500 mg at week 4,500 mg at week 8, and 500 mg at
week 12)
of the anti-TL1A antibody A219 can cover up to about 55 fold over-production
(fold
increase) of TL1A in the intestine of a patient. As shown in FIG. 15U,
administration of a
dose at 1000 mg D1, 500 mg W2, W4, W8, W12, (i.e. 1000 mg at day 1,500 mg at
week 2,
500 mg at week 4, 500 mg at week 8, and 500 mg at week 12) of the anti-TL1A
antibody
A219 can cover up to about 60 fold over-production (fold increase) of TL1A in
the intestine
of a patient. As shown in FIG. 15V, administration of a dose at 1000 mg D1,
500 mg W2,
W4, W6, W10, (i.e. 1000 mg at day 1, 500 mg at week 2,500 mg at week 4, 500 mg
at week
6, and 500 mg at week 10) of the anti -TL1A antibody A219 can cover up to
about 75 fold
over-production (fold increase) of TL1A in the intestine of a patient.
1005331 For comparison, a reference antibody that only binds to trimeric TL1A
was tested
in the whole-body PBPK model (reference antibody sequence, light chain SEQ ID
NO: 382
and heavy chain SEQ ID NO: 383). As shown in FIG 15W, such reference antibody
failed to
consistently reduce or consistently keep the free TL1A concentration in
diseased tissue of a
patient below the free TL1A concentration in the corresponding tissue of a
normal healthy
volunteer, when the diseased tissue overproduces TL by 50 fold or higher over
the TLIA
production in the corresponding tissue of a normal healthy volunteer. This is
in sharp
contrast with FIG. 15A, in which the anti-TL1A antibody A219 that binds to
both monomeric
TL1A and trimeric TL1A consistently reduced and kept free TL1A concentration
in the
- 264 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
diseased tissue below the free TLIA concentration in the corresponding tissue
of a normal
healthy volunteer, even if the diseased tissue overproduced TLIA by 100-fold
over the TLIA
production in the corresponding tissue of a normal healthy volunteer. As
described above
and shown in FIGS. 12C, 13C, and 14A-14B, the UC patients were determined to
have a 50-
fold overproduction of TLIA in the diseased tissue to recapitulate the
observed modest
increase in serum TL1A concentration. As such, an anti-TL1A antibody that
binds to both
monomeric and trimeric TL1A reduces the free TL1A concentration in the
diseased tissue of
a patient below the free TL1A concentration in the corresponding tissue of a
normal healthy
volunteer.
[00534] To further demonstrate the advantage of the anti-TL1A antibody that
binds to both
monomeric and trimeric TLIA in treating patients and reducing free TL1A
concentration in
diseased tissues, such antibodies were directly compared with a reference
antibody that only
binds to trimeric TLIA. As shown in FIGS. 15X-15Z, the anti-TL I A antibody
A219 that
binds to both monomeric and trimeric TLIA consistently and significantly
reduced the free
TLIA concentration in the diseased tissue b elow the free TLIA concentration
in the diseased
tissue resulted from the treatment of the reference anti-TL1A antibody that
binds to only
trimeric TLIA (reference antibody sequence, light chain SEQ ID NO: 382 and
heavy chain
SEQ ID NO: 383).
Example 21: Population PK (popPK) Models for Determining the Effective Dose
[00535] Additionally, based on the available PK data available from Example
16, a
population PK model was built to accurately simulate and predict A219 PK in
the population of
normal healthy volunteers. The available PK data were best described by a 2-
compartment model
with linear elimination. Demographic variables (including sex, age, race, and
body size related
variables) and laboratory clinical variables (including hematological, urine,
and chemical
variables) were tested for inclusion in the model for effect on the clearance
and the volume of
distribution in the central compartment. None of these variables were
identified as significant
covariates on the 2 PK parameters evaluated. The population PK parameter
estimates, and
standard error (SE) are described in Table 27. Residual variability of A219
concentrations
associated with the population PK model was 11.9%. Goodness of fit plots are
presented in
FIGS. 16A-16H. These plots indicated good correlations between population
predicted A219
concentrations ("Predicted DV") and observed A219 concentrations ("Observed
DV"), and
between individual predicted A219 concentrations ("IPRED DV") and Observed DV.
No bias in
standardized weighted residuals versus predicted concentrations or versus time
was noted.
Evaluation of the visual predictive check (FIG. 17A) indicated that the
population PK model
- 265 -

WO 2022/178159
PCT/US2022/016841
could adequately predict the observed A219 concentrations and was suitable to
be used to
simulate A219 concentrations.

1905361 Having established a popPK model, the popPK was used to select an
induction
dose to rapidly achieve steady state concentration. As shown in FIG. 17B, the
loading dose
of the induction regimen of 1000 mg at day 1, 500 mg at week 2, 500 mg at week
6, and 500
mg at week 10 ensures achievement of induction steady state concentration from
day 1.
Furthermore, as shown above in the whole-body PBPK, such an induction regimen
can
address over 100x over-production of TL1A in the colon within the first 5
weeks of induction
and over 60x over-production for the 12 week period.

Evaluate the Safety, Efficacy, and Pharmacokinetics of Induction Therapy with
A219 in
Subjects with Moderately to Severely Active Ulcerative Colitis.
1005371 To validate the efficacy of the anti-TL1A antibody A219 in ulcerative
colitis
(UC), a phase 2 clinical trial is conducted. The clinical trial includes an
induction period, as
shown in FIG. 18A, and an open-label extension (maintenance) period, as shown
in FIG.
18B. The detailed design of the clinical trial protocol is shown in the
protocol synopsis of
Table 28 below. The disclosure provides that clearance of free soluble TL1A
(sTL1A) from
the gut will translate into efficacy. Therefore, a physiologically based PK
model (as
described in Example 20) was used to predict the impact of various dosing
regimen of A219
on the level of sTL1A in normal and disease states in the central compartment
(serum) and
gut. The model predicts that the proposed induction regimen will lead to sTL1A
levels of
lower than healthy volunteers if the over-production level of sTL1A in the
colon is as high as
60-fold. After the 12-week induction, subjects who are in response will
continue in the open-
label extension randomized to 2 maintenance regimens. The maintenance regimen
of 250 mg

Q4W is selected to maintain the sTL1A level to below that of healthy
volunteers if the
production of sTL1A in the colon is up to 20 x and the 100 mg Q4W regimen is
selected to
maintain the sTL1A level to below that of healthy volunteers if the production
of sTL1A in
the colon is up to 10'.

The study has 4 periods (Screening Period, Induction Period [IP], Open-
Label Extension [OLE] Period, and Follow-Up [FU] Period). The study will
have 2 Cohorts that will enroll subjects in a sequential fashion utilizing an
adaptive design as described below.
Cohort 1: Following the Screening Period, approximately 120 eligible
subjects with moderately to severely active UC will enter the IP and be
randomized in a 1:1 fashion to receive intravenous (IV) administration of
A219 1000 mg on Week 0/Day 1, followed by 500 mg on Weeks 2, 6, and
10, or placebo at the same timepoints. Randomization will be stratified by
CDx status of positive (CDx+) or negative (CDx-) and prior biologic
experience (yes/no) at Week 0/Day 1. Subjects who discontinue from the
study will have a follow-up period of 12 weeks after last dose.
Cohort 2: When approximately 80% of Cohort 1 subjects (i.e., ¨96 subjects)
have reached Week 12 or early terminated from the study, the DMC will
conduct an unblinded analysis of clinical efficacy in CDx+ subjects and will
recommend whether an expansion to Cohort 2 is warranted. The planned
sample size for CDx+ subjects (combining Cohort 1 and Cohort 2) will be
approximately 40, in the case where Cohort 2 is initiated. For Cohort 2,
eligible subjects (who must be CDx+) will enter the IP and be randomized
in a 1:1 fashion to receive IV administration of A219 1000 mg on
Week 0/Day 1, followed by 500 mg on Weeks 2, 6, and 10, or placebo at
the same timepoints. Randomization will be stratified by prior biologic
experience (yes/no) at Baseline. Subjects who discontinue from the study
will have a follow-up period of 12 weeks after last dose.
Subjects who complete the 12-week IP from either Cohort will have the
option to enter OLE. During OLE, starting at Week 14 visit:
= Subjects who have achieved deep remission (defined as in clinical
remission [endoscopic subscore of 0 or 1, rectal bleeding subscore of 0, and
stool frequency subscore of 0 or 1 and not greater than Baseline] and RHI <
3) will continue in the study and have therapy withdrawal.
o Upon disease relapse (defined as rectal
bleeding score of >I, and either
hsCRP > 5 and/or fecal calprotectin > 250), subjects can receive another
course of induction therapy (1000 mg IV followed by 500 mg IV 2, 6, and
weeks after the first infusion) followed by maintenance therapy of 250
mg IV every 4 weeks (Q4W) for atotal of 50 weeks.
= Responders (defined as reduction from Baseline > 2 points and > 30%
in 3-component Modified Mayo Score, accompanied by a reduction > lin
rectal bleeding subscore or absolute rectal bleeding subscore < 1) who have
not achieved deep remission will be re-randomized, stratifiedby CDx status
of CDx+ or CDx-, to either 250 mg IV Q4W or 100 mg IV Q4W, starting at
Week 14 until Week 50.
= Nonresponders will receive an open-label induction regimen of
1000 mg of A219 on Week 14, followed by 500 mg on Weeks 16,20, and
24. Nonresponders who do not respond at Week 28 (per investigator
discretion) should be discontinued from the study.

will be re-randomized to either 250 mg IV Q4W or 100 mg IV Q4W,
starting at Week 28 for a total of 50 weeks.
The study may be amended by the Sponsor to extend the OLE period
beyond 50 weeks based on emerging safety data.
The study also includes an optional PK sub-study during the IP for subjects
who consent to additional PK sampling.
SAMPLE SIZE: The study is planned to randomize up to
approximately 170 subjects,
approximately 120 in Cohort 1 and up to 50 in Cohort 2. A sample size of
60 per arm in Cohort 1 will enable a statistical power of > 80% for the
primary endpoint at 1-sided significance level of 0.025 using Cochran-
Mantel-Haenszel (CMH), assuming clinical remission rate of 5% for
placebo and 24% for A219. Additionally, the sample size will confer
> 80% power to achieve statistical significance for the 1st secondary
endpoint of endoscopic improvement with an overall 1-sided alpha level of
0.025, assuming the endoscopic improvement rates are 15% and 38% for
placebo and A219 groups, respectively.
Additionally, for analyses of the CDx population (combining CDx+
subjects from Cohort 1 and Cohort 2), a sample size of 40 per arm will
provide a statistical power of? 80% at a 1-sided alpha level of 0.025,
according to a group sequential design with anon-binding futility interim
analysis when 18 subjects per arm reach Week 12, assuming clinical
remission rate of 5% for placebo and 31% for A219.
SUBJECT TYPE: Male or female subjects? 18 years of age with
moderately to severely
active UC.
FORMULATIONS: A219 will be supplied in 10 mL vials each
containing 500 mg A219(60
mg/mL solution) for IV administration after reconstitution.
DOSAGE: Subjects will be stratified by CDx+/CDx-
status and prior biologic
experience (yes/no) in a 1:1 ratio to:
= A219 1000 mg IV on Week 0/Day 1, followed by 500 mg IV on
Weeks 2, 6, and 10
= Placebo IV on Week 0/Day 1, followed by placebo IV on Weeks 2, 6,
and 10
During OLE:
= Deep remitters will enter the therapy withdrawal period
o All subjects who develop disease relapse after therapy withdrawal will
receive another course of induction therapy (1000 mg IV followed by 500
mg IV 2, 6, and 10 weeks after the first infusion) followedby maintenance
therapy of 25() mg IV Q4W fora total of50weeks.

Statistical Methods: Statistical methods will be detailed in the
Statistical Analysis Plan. The
SAP will provide details about the method of analysis and specific planned
analyses, and will be prepared and approved by Prometheus Biosciences
and its designees before study database lock and unblinding of subject
treatment assignments.
The analysis populations are defined as follows:
= Full analysis set (FAS) from Cohort 1: all subjects randomized and
treated in Cohort 1
= FAS for CDx+: all CDx+ subjects who are randomized and treated in
both Cohort 1 and Cohort 2
= Safety analysis set: all subjects treated
The following analyses will be performed:
Efficacy:
The efficacy assessment will test for the difference between A219 and
placebo groups in FAS.
"lhe primary endpoint will be analyzed and compared between A219 and
placebo treatment groups in FAS from Cohort 1. The primary endpoint, the
proportion of subjects achieving clinical remission, will be tested between
the 2 treatment groups at 1-sided significance level of 0.025 using CMH
with stratification factors at randomization. If significant, the lst
secondary
endpoint of proportion of subjects achieving endoscopic improvement will
be tested between the 2 treatment groups at 1-sided significance level of
- 279 -

WO 2022/178159
PCT/US2022/016841
0.025. If significant, the 2nd, 3rd, 4th, and 5th secondary endpoints will be
tested sequentially, each at 1-sided significance level of 0.025. Testing for
statistical significance will stop when the first endpoint is not
statistically
significant at level of 0.025 and all remaining p values will be nominal.
Treatment difference for primary and secondary endpoints for Cohort 1 will
be estimated along with 95% CI for all subjects in FAS. The secondary
endpoints in CDx+ subjects will be summarized and compared between
A219 and placebo groups in FAS for CDx-P, while the treatment difference
will be estimated with 95% CI. Additional efficacy analysis will be detailed
in SAP.
Interim Efficacy Analysis:
An interim analysis will be carried out when approximately 80% of
subjects (approximately 96 subjects) in Cohort 1 have reached Week 12 or
early terminated from the study. The DMC will review the unblinded
efficacy and safety data and recommend on the expansion to Cohort 2.
Decision rules to initiate Cohort 2 are determined according to the futility
bounds of group sequential design of a sample size of 40 per arm with one
interim analysis at the information fraction of 45%. Because the exact
bounds will be calculated using the actual number of subjects with CDx+
included in the interim analysis, the final decision rules, along with
sensitivity analysis, will be specified in the DMC SAP, prior to the interim
analysis.
Adverse Events:
AEs will be coded using the most current version of Medical Dictionary for
Regulatory Activities (MedDRA ).
A by-subject AE data listing, including verbatim term, preferred term (PT),
system organ class (SOC), treatment, severity, seriousness criteria,
relationship to drug, and action taken, will be provided.
The number of subjects experiencing treatment-emergent adverse events
(TEAEs) and number of TEAEs will be summarized by treatment using
frequency counts for Safety analysis set.
Medical History, chest x-ray, electrocardiogram (ECG), and physical
examination will be listed by subject.
Changes in ECGs and physical examinations will be described in the text of
the final report.
Concomitant Medications:
Concomitant medications will be coded using the most current World
Health Organization (WHO) drug dictionary and listed by treatment.
Pharmacokinetics:
Summary statistics of A219 concentrations and anti-drug antibody
(ADA) by visit and by CDx+ and CDx-.

Example 23: A Phase 2a, Multi-Center, Open-Label Study to Evaluate the Safety,
Efficacy, and Pharmacokinetics of A219 in Subjects with Moderately to Severely
Active
Crohn's Disease.
1005381 To validate the efficacy of the anti-TL1A antibody A219 in Crohn's
disease (CD),
a phase 2 clinical trial is conducted. The clinical trial includes an
induction period, as shown
in FIG. 19, and an open-label extension (maintenance) period, also shown in
FIG. 19. The
detailed design of the clinical trial protocol is shown in the protocol
synopsis in Table 29
below. The disclosure provides that clearance of free soluble TL1A (sTL1A)
from the gut
will translate into efficacy. Therefore, a physiologically based PK model (as
described in
Example 20) was used to predict the impact of various dosing regimen of A219
on the level
of sTL1A in normal and disease states in the central compartment (serum) and
gut. The
model predicts that the proposed induction regimen will lead to sTL1A levels
of lower than
healthy volunteers if the over-production level of sTL1A in the colon is as
high as 60-fold.
After the 12-week induction, subjects who are in response will continue in the
open-label
extension randomized to 2 maintenance regimens. The maintenance regimen of 250
mg Q4W
is selected to maintain the sTL1A level to below that of healthy volunteers if
the production
of sTL1A in the colon is up to 20x and the 100 mg Q4W regimen is selected to
maintain the
sTL1A level to below that of healthy volunteers if the production of sTL1A in
the colon is up
to 10x.

STUDY DESIGN: This is a multi-center, open-label, proof of
concept study designed to assess
the safety, tolerability, and preliminary efficacy of A219 following
12 weeks of induction therapy in subjects with Crohn' s disease (CD). This
study will be conducted under the aegis of a Data Monitoring Committee
(DMC) and will commence following the demonstration of an acceptable
safety profile of A219 at a dose of > 500 mg in the multiple ascending dose
study in normal healthy volunteers (Study PR200-101).
The study has 4 periods (Screening, IP, OLE and Follow-Up [FU] Period).
Following the Screening Period, approximately 50 eligible subjects with
moderately to severely active CD will enter the IP to receive A219 1000 mg
on Week 0/Day 1, followed by 500 mg on Weeks 2, 6, and 10 via
intravenous (IV) administration. Subjects who discontinue from the study
will have a follow-up period of 12 weeks after the last dose.
Response at Week 12 will be defined as reduction from Baseline in CDAI
of? 100 points. Non-responders at Week 12 should discontinue from the
study.
Subjects who complete the 12-week IP and have responded will have the
option to enter OLE. Subjects will continue in OLE until they progress,

withdraw from the study, study termination, or Week 50. During the OLE,
starting at Week 14 visit:
= Subjects who achieved deep remission (defined as clinical remission
with CDAI < 150, endoscopic remission with SES-CD < 4 with none of
the segments with score of more than 1, and RHI < 3) will continue in the
study and have therapy withdrawal
o
Upon disease relapse (defined as CDAI > 220 and either hsCRP
> 5 mg/L and/or fecal calprotectin > 250 g/g), subjects can receive
another course of induction therapy (1000 mg IV followedby 500 mg IV 2,
6, and 10 weeks after the first infusion) followed by maintenance therapy
of 250 mg IV every 4 weeks (Q4W) for atotal of 50 weeks
= Other subjects will be re-randomized to either 250 mg IV Q4W or
100 mg IV Q4W until Week 50
The study may be amended by the Sponsor to extend the OLE period
beyond 50 weeks based on emerging safety data.
SAMPLE SIZE: The study is planned to enroll approximately
50 subjects. The sample size
will enable a statistical power of 80%, at 1-sided significance level of
0.025,
to test against the null hypothesis of endoscopic improvement rate of12%,
assuming the endoscopic improvement rate for A219 is 27%.
SUBJECT TYPE: Male or female subjects > 18 years of age
with moderately to severely
active CD.
FORMULATIONS: A219 will be supplied in 10 mL vials each
containing 500 mg A219(60
mg/mL solution) for IV administration after reconstitution.
DOSAGE: Induction Period: all subjects will receive
A219 1000 mg on Week
0/Day 1, followed by 500 mg IV on Weeks 2,6, and 10.
Non-responders at Week 12 should be discontinued from the study.
Responders at the end of Week 12 have the option to enter the OLE, where
subjects with deep remission will undergo therapy withdrawal and subjects
without deep remission will be randomized to receive one of the following
regimens until disease progression, withdraw from the study, study
termination, or Week 50:
= A219 250 mg IV on Week 14 then Q4W
= A219 100 mg IV on Week 14 then Q4W
Subjects who do not respond by the end of Week 12 should be discontinued
from the study.
All subjects who develop disease relapse (defined as CDAI > 220 and either
hsCRP > 5 mg/L and/or fecal ealprotectin > 250 g/g), after therapy
withdrawal will receive another course of induction therapy (1000 mg IV
followed by 500 mg IV 2, 6, and 10 weeks after the first infusion) followed
by maintenance therapy of 250 mg IV Q4W for a total of 50 weeks.
ROUTE OF The study drug will be reconstituted in 250
mL of 0.9% normal saline (NS)
ADMINISTRATION: and will be administered IV over 30 minutes.

Statistical Methods: Statistical methods will be detailed in the
Statistical Analysis Plan (SAP).
The SAP will provide details about methods of analysis and the specific
planned analyses, and will be prepared and approved by Prometheus
Biosciences and its designees before study database lock.
The analysis populations are defined as follows:
= Full analysis set (FAS): all subjectstreated with Baseline SES-CD score
= Safety analysis set: all subjects treated
The following analyses will be performed:
Efficacy:
The primary efficacy endpoint, endoscopic improvement at Week 12, will
be used to assess the efficacy of A219. The proportion of subjects in FAS
with endoscopic improvement will be tested against the null hypothesis of
endoscopic improvement rate of 12%, at a 1-sided significance level of
0.025. If significant, the 1st secondary endpoint of proportion of subjects
achieving clinical remission will be tested against the null hypothesis of
clinical remission rate of 16%, at a 1-sided significance level of 0.025.
The point estimates for the primary and secondary endpoints will be
calculated along with 90% confidence interval for FAS and by companion
diagnostic (CDx) status (CDx+ or CDx-).

Example 24: Formulation Verification Study.
1005401 Exemplary formulations provided herein were placed on long-term
stability
studies (up to six months). This Example summarizes the results of these
storage stability
studies.
1005411 Materials used in this study include A219 at various concentrations as
indicated.
1005421 METHODS AND PROCEDURES
1005431 UV Analysis. The sample absorbance and sample concentration were
measured
by standard UV absorbance instrument, using an extinction coefficient of
1.41mL. mg-1 cm-
1, and correcting background scattering.
1005441 pH Analysis. Before the start of analysis, the pH probe was calibrated
with three
pH standards ordered from fisher. The pH of the formulation will be measured
by inserting
the pH probe into the sample and waiting until the measured value has
stabilized, which can
take up to 1 to 2 minutes.
1005451 Osmotic Analysis. The osmotic analysis was performed using an Advanced

Instruments Osmo 1. At the start of analysis, a reference standard at 290 mOsm
is analyzed to
ensure the instrument is working properly. After the reference standard has
passed the
samples are then analyzed. 20uL of sample material is removed and analyzed by
the Osmo 1.
1005461 Viscosity. The viscosities of the samples were measured using m-Vroc
from

Rheosense (San Ramon, CA, USA). The dynamitic viscosity of sample was
calculated by
flowing the samples past three difference pressure sensors. The linear
regression of the
pressure drop from the three sensors was then used to calculate dynamitic
viscosity of the
samples. The instrument was calibrated and the dynamitic viscosity of the
samples were
measured according to manufacturer's instructions and industry standards. The
analysis
parameters for sample concentrations ranging from 60 to ¨230 mg/mL are listed
in Table 30:

[00548] Cation Exchange Chromatography (CEX). The CEX was also used to measure

the stability of the protein samples.
[00549] Flow Imaging (FlowCam). Measurements of particle counts in the samples
were
made using a Model VS-1 FlowCAM flow imaging system (SN 551) with Sony SX90
camera and C70 pump with a 1 mL syringe (Fluid Imaging Technologies). The
system
qualification consisted of obtaining acceptable bead counts using an NIST
certified count
standard (PharmTrol, Thermo, catalogue no. CS3800-15 or similar) along with
acceptable
procedural blanks (water). The acceptance criteria used for the count standard
was 3800
15% and no more than 1 count/mL greater than or equal to 10 lam for the water
blank.
Samples were visually assessed during the sample run and if needed adjustments
were made
to optimize the results of each run. An x-y flow plot was recorded for each
sample run.
[00550] Study Design. The verification study examined formulations with A219
concentrations ranging from 60 to 200 mg/mL as shown in Table 31 (formulations

1005511 RESULTS
[00552] The control (TO) samples listed in Table 31 were characterized by
visual
inspection, osmolality (osmo), pH, protein concentration, viscosity, SEC, CEX
and Flow
Cam. The remaining times were analyzed by SEC and CEX except that the last
time point of
each temperature in Table 32 was characterized by the same measurements in TO.
[00553] Visual Characterization
1005541 The bulk material used for these studies had a slight yellow
tint, but was otherwise
clear with no visual particles observed. The formulations at TO were visually
inspected and
were clear with no visible particles observed. At 60 mg/mL, formulations 1 and
2, had slight
yellow tint, the tint became more intense as the concentration increased from
60 mg/mL to
200 mg/mL. A summary of the visual observations can be found in Table 33.
Throughout the
study, no visible particles were observed and the samples remained clear under
all conditions.

[00555] Osmo/a/i0;
[00556] The osmotic pressure was measured for the stability samples at TO, 3
and 6
months (Table 34). In addition, the theoretical osmolality was calculated for
all formulations,
except for formulation 1. The osmotic pressure for the samples ranged from 223
to 487
mOsmol/kgH20 for the highest protein concentrations (Table 34). The
differences in the
osmotic pressure between theoretical and measured become larger as the protein
concentration increased from 60 to 200 mg/ml, reflecting the increasing
contribution from the
protein. Overtime, the osmolality values do increases slightly for some
formulations (FIG.
20), but the differences are relatively minor.

[00557] Protein Concentration
[00558] The A219 protein concentration was measured to evaluate the stability
of samples
at TO, 3 and 6 months as shown in Table 35. Most of the values appear to be
unchanged
within the estimated error of the protein concentration method, indicating
that the A219 is
stable in these formulations (Table 35 and FIG. 21). The plot of the measured
A219 protein

concentrations are
fairly constant and likely do not reflect any substantive changes in protein
content (FIG. 21).
Moreover, the protein concentrations were all within 5% of the target
concentration for the
formulation.

[00563] For formulations 6-8, the viscosity data ranges from about 5.3 to 13.4
mPa*s as
protein increased from -150 to -200 mg/mL. By comparison, formulations 3-5
have a
somewhat higher viscosity, ranging from about 6.3 to 16.0 mPa*S over the same
protein
concentration range. Upon storage, some of the formulations do exhibit
slightly higher
viscosity values, possibly due to slightly increased levels of aggregates (see
below).

[00564] Stability measurements by Size Exclusion Chromatography (SEC)
[00565] The stability of the A219 samples was characterized by size exclusion
chromatography (SEC). At TO, the monomer content was >98% for these samples
(Table
38). After two months at 25 C, the monomer content only slightly decreases,
with all
formulations retaining > 97% monomer. Even after three months at 25 C, the
monomer
contents remain near 97%. When stored at 5 C, the loss of monomer (primarily
due to
formation of higher molecular weight (HMW) species) averages only about 0.2-
0.4% (Table
39).

appears that
formation of aggregates (HMW species) is increased som ewhat at higher
concentrations for
high concentration formulations 3-8. The overall monomer loss per month for
samples stored
at 5 C is only about 0.04 to 0.06% FIG. 24B. The monomer levels for the 25 C
samples are
provided in FIG. 24C. The average loss per month for these samples is about
0.3 to 0.4% per
month as shown in FIG. 24D. Based on these data, there would be less than 1%
loss of
monomer at 5 C over two years and less than 5% loss of monomer when stored at
25 C.

1005671 Stability measured by Cation Exchange Chromatography (CEX)
1005681 The stability of the A219 samples were characterized by cation
exchange
chromatography (CEX). The CEX data for the 0, 1, and 2 month time points are
summarized
in Table 40. The relative area of the main peak started near 65%. Overtime,
this decreased,
primarily due to increases in the acidic species, indicating some hydrolytic
change, such as
deamidation, was occurring. Formulation 1 (F01) shows the greatest changes.

1005691 After three months at 25 C, the main peak averaged near 51%, while
FOI
continues to show greater decrease with only about 46% main peak relative area
(Table 41).
By comparison, samples stored at 5 C exhibit very little decrease in CEX
measurements.
Even after six months, the relative area of the CEX main peak remains near 63%
for
formulations 2-8. Changes in the relative area of the CEX main peak are shown
in FIG. 25A.
Meanwhile, all of the high concentration (A219 at or above 150 mg/ml)
formulations showed
comparable stability by CEX. The rate of loss at 5 C is provided in FIG. 25B
and
formulations 2-8 have very good stability as determined by CEX.
1005701 The CEX stability profiles at 25 C are seen in FIG. 25C. The decrease
in the
main peak, presumably by hydrolytic changes, are more pronounced at 25 C than
at 5 C.
The rates of decrease per month at 25 C are about 20 times greater than at 5
C (FIG. 25D).
1905711 Stability Measurements by FlowCAM Flow Imaging Analysis
1005721 The stabilities of these samples were characterized by FlowCAM, which
counts
the number of subvisible particles (SVPs) in various size bins. The levels of
SVPs are all
reported in particle per mL. At TO, the particle counts are higher for F01
than the other
formulations (Table 42). However, at one month/5 C, the particle levels for
F01 were not
comparable to the other preparations. Results for the FlowCAM analysis for
samples held at
25 C after one and two months are shown in Table 43. Levels in all of the
formulations

remain relatively low after two months at 25 C (Table 43) and three months as
well (Table
44). The SVP levels for samples held at 5 C for three months appear to be
even slightly
lower than for the corresponding 25 C samples (Table 44). Finally, samples
held for six
months at 5 C were analyzed, and the levels of SVPs remained low as shown
(Table 45).

[00573] PLS Analysis for the 2 Month Samples
[00574] The 25 C 2 month data was used to constructed the PLS models. The
first PLS
model used the Loss MP by SEC after two months at 25 C as the endpoint (FIG.
26A). The
correlation coefficient for the calibration set was 0.975 while the r-value
for the validation set
was 0.776, indicating a model of reasonable quality. The PLS model indicates
the significant
factors influencing the stability of A2 19 include protein concentration,
sucrose, etc.
[00575] This model indicates that monomer loss (e.g., aggregation)
is greater at higher
protein concentrations (FIG. 26B). This effect is much more pronounced than
the pH effect.
The model predicts that lower pH and addition of acetate buffer reduces
monomer loss upon
storage at 25 C (FIG. 26C). Both sucrose and Lys were found to be effective
stabilizers
against aggregation (FIG. 260), while the impact of NaC1 and Gly is small
(FIG. 26E).
1005761 Eight different formulations were placed in longer-term storage at 5
C and 25 C,
and evaluated. Using the acetate buffer system, the pH of each acetate
formulation remains
essentially unchanged upon storage. As for the high concentration A219
samples, the
formulations with sucrose/NaCl clearly reduced viscosity relative to the
sucrose/Lys
formulations, corresponding to about ¨3 cP at 200 mg/ml. The rate of loss of
monomer for
samples in the formulations 2-8 stored at 5 C is quite small, with a total
loss of monomer
after two years predicted to be <1% for all of the high concentration
formulations.
[00577] These compositions appear to have little proclivity to form
particles. There is no
evidence of formation of visible particles and levels of SVPs remains low,
even after six
months of storage. Overall, these high concentration formulations appear to be
quite stable
and they appear to support the use of a 200 mg/ml formulation.

[00578] An Exemplary A219 formulation (60 mg/mL A219 in 20 mM sodium
phosphate,

5% (w/v) sucrose, 85 mM glycine, 0.01% (w/y) polysorb ate 20, pH 6.5) was
placed on long-
term stability studies. This Example summarizes the results of the storage
stability studies for
such exemplary formulation.
[00579]
The long-term stability condition tested for anti-TL1A (e.g. A219) was 5+3 C
(Upright). Accelerated stability condition at 25 C/60% RH (Upright) was also
performed. Testing
is performed per the stability protocol presented in Table 46 and Table 47
below. The methods
used for stability testing and acceptance criteria are presented in Table 48
and Table 49. In
addition, a full ICH stability study was also performed for the A219
formulation listed in this
Example (ICH referring to International Council on Harmonization of Technical
Requirements for
Pharmaceuticals for Human Use).

[00581] Results from the stability study are shown in Table 50, Table 51, and
Table 52.
Briefly, no significant change in A219 protein quality was observed for up to
12 months of
storage at -20 C or 2-8 C and there have been no out of specification findings
or changes in
the key analysis parameters. The antigen binding affinity and biological
activity are well
preserved at the 6 month, 25 C time point. The biophysical changes seen
indicate that the
formulation is suitable for A219 monoclonal antibody at elevated storage
temperatures for
prolonged periods.

Example 26: Results of Phase I Clinical Studies on Safety, PK, PD, and
Immunogenicity.
[00583] A phase I clinical study was completed to assess the safety, PK, PD,
and other
parameters for the anti-TL1A antibody (e.g. A219). The Phase I clinical study
tested double-
blind, randomized, placebo-controlled, single dose followed by multiple dose.
In the Single
Ascending Dose (SAD) cohort, the anti-TL1A antibody (e.g A219) was tested in a
total of 46
subjects with 3 to 1 randomization (35 to 11) in each dosing cohort. 6 cohorts
(e.g. 6 dose
levels) were tested for the SAD, which were 5 mg, 25 mg, 100 mg, 300 mg, 600
mg, and
1000 mg, with a follow-up period of 14 weeks. In the Multiple Ascending Dose
(MAD)
study, the anti-TL1A antibody (e.g. A219) was tested in 23 subjects with 3 to
1
randomization (17 to 6) in each dosing cohort. In the MAD study, all subjects
received 3
doses at days 1, 15, and 29. 3 cohorts (dose levels) were tested for the MAD
study, which
were 50 mg, 200 mg, 500 mg, with a follow-up period of 18 weeks. The phase I
clinical
study evaluated the safety and tolerability, pharmacokinetics (PK),
immunogenicity (e.g., by
evaluating the anti-drug antibodies, ADA), and pharmacodynamic (PD) markers of
the anti-
'TL1A antibody (e.g. A219).
[00584] 68 out of the 69(98.5%) subjects completed the study and follow-up
period, with
one patient completed up to Week 8 in the 200 mg MAD but lost to follow-up. No
serious
adverse events (SAE) was observed in the clinical study. Neither drug-related
infusion
reactions nor drug-related extension in infusion time was seen during the
study (with 30-minute
infusions of up to 1000mg). No clinically significant changes were reported in
physical exam,
lab values, electrocardiogram, or vital signs.
[00585] All adverse events (AEs) assessed as related to study drug were mild.
Exemplary
mild AEs reported in the SAD study include 1 report of somnolence in the 35
subjects tested
with A219 (at the 600 mg dose) and 1 report of headache in the 11 subject
placebo group.
Exemplary mild AEs reported in the MAD study include: 1 report of diarrhea in
the 17
subjects tested with A219, 1 report of diarrhea in the 6 subject placebo
group, 1 report of
somnolence in the 17 subjects tested with A219, 1 report of dizziness in the
17 subjects tested
with A219, and 1 report of headache in the 11 subject placebo group.
[00586] Therefore, the anti-TL1A antibody (e.g. A219) has favorable safety and

tolerability.
[00587] Various PK parameters were determined and shown in FIGS. 27A and 27B,
and
Tables 55-59.

of the anti-TLIA antibody (e.g. A219) meets the PK performance standards for a
therapeutic
antibody and supports the phase 2 dosing regimen discussed in Section 5
(Examples). The
half-life after a dose of 500 mg every other week is about 19 days. Dose
proportional
exposure at doses greater than or equal to 100 mg was observed in the PK
profile.
1005891 Furthermore, target engagement was assessed by determining the soluble
TLIA
concentration in the serum of the subjects in the clinical studies. The anti-
TL1A antibody
A219 provided herein demonstrated dose-dependent, robust, sustained target
engagement as
shown in FIGS. 28A and 28B. Target engagement as determined by the increase in
the
soluble TL1A in serum maximized at 200 mg A219 Q2W at about 45,000 pg/mL sTL1A

(FIG. 28B). Such a target engagement is more than 4 fold higher than observed
in the control
reference anti-TL1A antibody that only binds to trimeric TL1A (control
reference antibody
sequence, light chain SEQ ID NO: 382 and heavy chain SEQ ID NO: 383) (see
Banfield C, el
al. Br J Clin Pharmacol. 2020;86:812-824; Danese S, et al. Clin Gastroenterol
Hepatol. 2021
Jun 11;S1542-3565(21)00614-5; Danese S, etal. Clin Gastroenterol Hepatol. 2021

Nov;19(11):2324-2332.e6). Therefore, the anti-TL1A antibody provided herein
that binds to
both monomeric and trim eric TL1 A provide superior target engagement over the
anti-TL1 A
antibody that binds to only trimeric TL1A.
1005901 Additionally, immunogenicity of the anti-TL1A antibody is assessed by
determining the anti-drug antibody (ADA). At clinically relevant dose (1000 mg
SAD, 200
mg and 500 mg MAD), immunogenicity rate was no more than 20%. In contrast, the

reported immunogenicity (e.g., ADA positivity) rate for the control reference
anti-TL1A
antibody (light chain SEQ ID NO: 382 and heavy chain SEQ ID NO: 383) was over
80% at
similar doses in both normal healthy volunteer and UC patients (see Banfield
C, et al. Br J
Clin Pharmacol. 2020;86:812-824; Danese S, et al. Clin Gastroenterol Hepatol.
2021 Jun
11; S1542-3565(21)00614-5; Danese S, et al. Clin Gastroenterol Hepatol. 2021
Nov;19(11):2324-2332.e6). ADA titers observed in the clinical trial were
inversely
proportional to A219 exposure and ADA positivity only occurred at low A219
concentrations.
1005911 To further evaluate the potential impact of ADA, neutralizing antibody
was also
determined in the phase I trial. Neutralizing antibody rate at clinically
relevant dose was
uncommon and was observed only in 1 out of 17 subjects (6%) across the
clinically relevant
dose groups (1000 mg SAD, 200 mg and 500 mg MAD). Immunogenicity observed in
the
phase I trial was not clinically relevant in that (1) ADA did not impact
safety because there
were no report of infusion reaction throughout the study, (2) ADA did not
impact clearance

WO 2022/178159
PCT/US2022/016841
of A219 in the population PK model, and (3) ADA did not impact target
engagement because
there was no apparent impact on sTL1A level as shown in FIGS. 28A and 28B.
1005921 In summary, the anti-TL1A antibody provided herein has favorable
safety and
tolerability; PK of the anti-TL1A antibody provided herein meets performance
standards and
supports phase 2 dosing regimen; the anti-TL1A antibody provided herein
neutralizes both
active trimeric TL1A and inactive monomeric TL1A, leading to increased and
sustained
target engagement and potentially to more effective reduction of active TL1A
in tissues; the
anti-TL1A antibody provided herein do not trigger immunogenicity that may
adversely
impact its therapeutic efficacy.
Example 27: Further validation of physiologically based pharmacokinetic (PBPK)

modeling and population pharmacokinetic modeling (popPK) with the phase I
clinical
trial results.
1005931 Based on the PK, PD, and TL1A concentration data from the subjects of
the phase
I clinical trial, further PBPK modeling, popPK modeling, and validation of the
models were
conducted. As further described above (e.g. in this Section 5 (Examples)), the
key
mechanisms included in the PBPK models include: central, peripheral, and
diseased ti ssue
(e.g. gut) compartment; TL1A synthesis and clearance, interchange between
trimer and
monomer states; upregulated TL1A synthesis in disease gut tissue of IBD
patients; binding
by A219 to both monomer and trimer TL and binding a control reference antibody
only to
trimer TL1A; administration, distribution, non-specific elimination, and
membrane TL
mediated target mediated drug disposition for the anti-TL1A antibodies;
distribution and
clearance of bound complexes. The inputs to the PBPK model include: (1) the
anti-TL1A
antibody provided herein binds to both TL monomer and trimer, whereas the
control
reference antibody (light chain SEQ ID NO: 382 and heavy chain SEQ ID NO: 383)
binds
only to TL1A trimer; (2) TL1A is synthesized systemically in the peripheral
compartment in
healthy subjects and in inflamed gut tissue, and the elevated tissue
expression of TL1A is
caused by increased synthesis of TL1A within the diseased tissue; (3) trimer
TL1A and
monomer TL1A interchange at a rapid equilibrium, resulting in a fixed steady
state ratio of
monomer to trimer; (4) TL1A trimers/monomers bound to drug do not change
forms; (5) the
anti-TL1A antibody binds trimer or monomer with the same effective Kd in a
single binding
event; (6) free TL1A monomer and trimer clear at different rates; (7) antibody
bound TL1A
monomer and antibody bound TL1A trimer clear at the same rate; (8) antibody
bound TL1A
monomer and antibody bound TL1A trimer distribute the same as the antibody;
antibody
bound to membrane TL1A internalizes at the same rate as membrane TL1A. The

1005941 For validation of the model, the model was fit to the SAD data and
benchmarked
to Q2W data of the phase I clinical trial with A219. As shown in FIGS. 29A and
29B, the
model fitted to single ascending dose data of A219 with reasonable agreement.
Furthermore,
as shown in FIGS. 29C and 29D, the model was able to capture multiple
ascending dose data
of A219 without additional fitting, indicating the consistency and robustness
of the model.
Similarly and without additional fitting, the model captured the data of a
control reference
- 315 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
antibody that binds only to TL1A trimer (light chain SEQ ID NO: 382 and heavy
chain SEQ
ID NO: 383) with regard to (1) phase I single ascending dose data (FIGS. 29E
and 29F), (2)
phase I multiple ascending dose data (FIGS. 29G and 29H), and (3) phase II
data on PK &
total sTL1A levels (FIGS. 291 and 29J) (Banfield C, et al. Br J Clin
Pharmacol. 2020;86:812-
824. Danese S, et al.. :Clin Gastroenterol Hepatol. 2021 Nov;19(11):2324-
2332.e6, Hassan-
Zahraee M, etal. Inflammatory Bowel Diseases 2021, XX, 1-13). The IBD specific

parameters were then calibrated to capture free tissue TL 1 A levels in the
gut (FIG. 29K) as
observed with the control reference antibody (light chain SEQ ID NO: 382 and
heavy chain
SEQ ID NO: 383) in clinical trials. As such the model was validated with the
clinical trial
data.
1005951 This validated model can be used to determine the dose to reduce the
free TL1A
concentration in the patient's diseased tissue to below the TL1A concentration
of the
corresponding tissue in a healthy subject, similar to that described above in
Example 20 and
21. FIG. 30A and 30B show examples of such doses determined from the validated
model
that can bring the free TL1A concentration in the patient's diseased tissue to
below the TL1A
concentration of the corresponding tissue in a healthy subject (IV 4x= 1000 mg
loading
dose, 3 500 mg on days 14,42, 70; SC dosing 240 mg Q1W or Q2W).
1005961 The validated model also confirmed that anti-TL1A antibodies that bind
to both
TL1A monomer and trimer can engage more TL1A in circulation and result in
greater
reduction of TL1A in diseased tissue than anti-TL1A antibodies that only bind
to TL1A
timer. In a head-to-head comparison in the validated model, anti-TL1A
antibodies that bind
to both TL1A monomer and timer engaged more TL1A in circulation than anti-TL1A

antibodies that only bind to TL1A trimer as shown in FIG. 30C, with the
circulation TL1A
accumulation ratio determined to be 3.5 fold. In a head-to-head comparison in
the validated
model, anti-TL1A antibodies that bind to both TL1A monomer and trimer also
resulted in
higher percentage of TL1A reduction of TL1A in diseased tissue (about 100%
reduction from
day 0) when compared to anti-TL1A antibodies that only bind to TL1A trimer, as
shown in
FIG. 30D. Because the diseased tissue of IBD patients often produces 20,30,
40,50, 60,70,
or even 100 fold more TL1A as shown in Examples 20 and 21 above, a few
percentage point
of residual TL1A production in the diseased tissue of the patients can still
be a pathological
TL1A concentration.
1005971 Similarly, popPK model was further fitted and validated
with the phase I clinical
trial data. Briefly, 2 compartment popPK Model for A219 with linear and non-
linear
elimination (target-mediated drug disposition) was established as shown in
FIG. 31A and as
- 316 -
CA 03207817 2023- 8-8

WO 2022/178159
PCT/US2022/016841
described above. No covariates were found to have a clinically relevant effect
on PK
parameters. The popPK model fitted the phase I clinical trial data well and
reliably predicted
A219 and TLIA concentration data in the tested population, as shown in FIGS.
31B-31E.
Further, there was no apparent bias between the predicted and observed A219
and TL1A
concentrations (FIGS. 31B-31E).
1005981 Having validated the popPK model, the popPK model was used to
determine
A219 and TL IA concentrations under various dosing regimen. The validated
popPK model
confirmed the dose to achieve the levels of anti-TLIA antibody concentration
and
engagement of TL I A in the serum (total soluble TL I A concentration in
circulation) in order
to lower the TLIA concentration in the diseased tissue to below that of a
healthy subject, as
shown in FIGS. 3 2A-3 2H.
